HTML with Javascript - Apply grayscale to images in a table, then mouseover images to go back to colored version

I had a question about using the mouseover / mouseout event in javascript along with applying grayscale to a table. The question says that I must first making an image grid (table) all gray in html. Then I need to add javascript to the html so that when I mouse over the image, the image turns into a colored image, and when I mouse out from the image, the image reverts back into a gray image. The problem said no CSS is allowed, so only using javascript and html, if possible.
Thank you so much in advance for the help, I really appreciate it!
Here is some of my code below (the table images need to start from grayscale, then apply/remove the grayscale when using the mouseover event. So far the mouseover effect only works on the first image. And I also don't know how to apply a grayscale filter over the whole table first).
function image_grayscale() {
document.getElementById("image").style.filter = "grayscale(100%)";
}
function remove_grayscale() {
document.getElementById("image").style.filter = "grayscale(0%)";
}
<div class="table">
<table border="3" align=center width="600" height="200">
<tr style="width:1" ;style="height:10%" ; bgcolor="white">
<td onmouseover="remove_grayscale()" onmouseout="image_grayscale()">
<img id="image" src="https://picsum.photos/id/1067/100/100" width="100" height="100" />
</td>
<td onmouseover="remove_grayscale()" onmouseout="image_grayscale()">
<img id="image" style="grayscale" src="https://picsum.photos/id/1067/100/100" width="100" height="100" />
</td>
<td onmouseover="remove_grayscale()" onmouseout="image_grayscale()">
<img id="image" src="https://picsum.photos/id/1067/100/100" width="100" height="100" />
</td>
<td onmouseover="remove_grayscale()" onmouseout="image_grayscale()">
<img id="image" src="https://picsum.photos/id/1067/100/100" width="100" height="100" />
</td>
<td onmouseover="remove_grayscale()" onmouseout="image_grayscale()">
<img id="image" src="https://picsum.photos/id/1067/100/100" width="100" height="100" />
</td>
<td onmouseover="remove_grayscale()" onmouseout="image_grayscale()">
<img id="image" src="https://picsum.photos/id/1067/100/100" width="100" height="100" />
</td>
</tr>
</table>

An id attribute must be unique.
Don't clutter the HTML more than necessary. It should be really easy to read.
Use addEventListener instead of onmouseover.
Method names are usually written with kebabCase (see the new method I added).
Don't repeat code. Instead, refactor similar code into a new method.
let table = document.getElementById('greyscaleTable')
table.addEventListener('mouseover', remove_grayscale);
table.addEventListener('mouseout', image_grayscale);
function image_grayscale(event) {
let element = event.target;
changeGrayscale('100%', element);
}
function remove_grayscale(event) {
let element = event.target;
changeGrayscale('0%', element);
}
function changeGrayscale(amount, element) {
let isGrayscaleImage = element.classList.contains('grayscale');
if (isGrayscaleImage) {
element.style.filter = `grayscale(${amount})`;
}
}
#greyscaleTable img {
width: 100px;
height: 100px;
}
<div id="greyscaleTable" class="table">
<table border="3" align=center width="600" height="200">
<tr>
<td>
<img class="grayscale" style="filter: grayscale(100%)" src="https://picsum.photos/id/1067/100/100" />
</td>

I'd personally suggest the following:
// define the function as a constant, using Arrow syntax;
// here we take the Event Object ('evt', passed from the (later)
// use of EventTarget.addEventListener(). From the Event-Object
// we retrieve the element to which the function was bound
// (evt.currentTarget), and update its CSSStyleDeclaration
// for the filter() function.
// We use a template-literal string (delimited with back-ticks
// to interpolate the JavaScript into the string, using the
// ${JavaScript here} notation.
// Based on the event-type we return the arguments of either
// 0 or 1; if the evt.type is exactly 'mouseenter' 0 is
// returned from the conditional operator, otherwise 1 is
// returned:
const toggleGrayscale = (evt) => evt.currentTarget.style.filter = `grayscale( ${evt.type === 'mouseenter' ? 0 : 1} )`,
// here we retrieve a NodeList of all <img> elements within the document:
images = document.querySelectorAll('img');
// we iterate over the NodeList of images to set them to
// grayscale(), initially:
images.forEach(
(img) => img.style.filter = "grayscale(1)"
);
// we iterate again (as Array.prototype.forEach() has no
// return value; here we use EventTarget.addEventListener()
// to bind the toggleGrayscale function for both the
// 'mouseenter' and 'mouseleave' events:
images.forEach(
(img) => {
img.addEventListener('mouseenter', toggleGrayscale)
img.addEventListener('mouseleave', toggleGrayscale)
});

How to change img src with a transition by clicking another image

So I'm on a project which requires me to use table, and forbids me to use any div tag.
I want to make a slider in one row of my table.
I want the image to change with a click on other image in the second row.
I've managed to do that using this code:
function changeImage(a) {
document.getElementById("imgblockjs").src=a;
}
And the html:
<HTML>
<HEAD>
<TITLE>
Home -- RTR
</TITLE>
<LINK REL="ICON" TYPE="IMAGE/PNG" HREF="../img/logo.png" />
<SCRIPT src="../script.js"></SCRIPT>
</HEAD>
<BODY>
<table border="0" width="100%" height="10px" cellspacing="0">
<tr>
<td colspan="4" >
<img id="imgblockjs" src="../img/singa.jpg" width="100%" height="300px" />
</td>
</tr>
<tr>
<td colspan="4" id="imgchanger">
<img src="../img/singa.jpg" id="imgthumb1" onclick="changeImage('../img/lion.jpg');">
<img src="../img/gajah.jpg" id="imgthumb2" onclick="changeImage('../img/elephant.jpg');">
</td>
</tr>
</table>
</BODY>
</HTML>
But that code doesn't have any transition.
I've tried using jquery:
$("#imgthumb1").click(function() {
$("#imgblockjs").fadeOut(1000, function changeImage(a) {
document.getElementById("imgblockjs").src=a;
}).fadeIn(1000);
return false;
});
I'm actually very new to jquery and haven't learn all the basics, I got the above jquery code on the internet and modified it a bit, thinking it would work. But it doesn't.
Can someone fix it? Or maybe use a different code? Basically I want the attribute src to be changed instead of having images on top of another. But if it's not possible, I'm open to any suggestion.
Also if possible I planned to make the picture change every 5 seconds automatically, using transition. But my first question is the priority
Thanks in advance

You can change that images dynamically using JQuery
I have added the classes to the images so that I can access them using class
Main Image: added class "fullimage"
small Images: added class "changeimage"
$('.changeimage').click(function(){
//getting the current clicked image source
var clickedItemImage=$(this).attr('src');
//setting the src of your main image
$(".fullimage").attr('src',clickedItemImage);
});
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<table border="0" width="100%" height="10px" cellspacing="0">
<tr>
<td colspan="4" >
<img id="imgblockjs" class="fullimage" src="../img/singa.jpg" width="100%" height="300px" />
</td>
</tr>
<tr>
<td colspan="4" id="imgchanger">
<img class="changeimage" src="../img/singa.jpg" id="imgthumb">
<img class="changeimage" src="../img/gajah.jpg" id="imgthumb">
</td>
</tr>
</table>
I hope it helps :)

$("img").on("click", function(){
$("#imgblockjs").fadeOut(1000, function() {
$("#imgblockjs").attr("src",this.src);
}.bind(this)).fadeIn(1000);
});
If an image is clicked, change the #imgblockjs.src to this images src...

How to Exclude specific images from JavaScript Photobox animation in a div?

I am using photobox to display all images within a div in a nice gallery style. However I want to include an image in the div that I do not want in the gallery, a PDF icon, which onlick will download a pdf file. At the moment this icon appears in the gallery when clicked, I would like to know how to exclude maybe a section of the div.
Here is my code
<div id="gallery">
<td width="226" align="right"><table width="206" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="199" align="center"><img src="images/GrndFloor_dimension_th.jpg" alt="Ground Floor" width="182" height="182" border="0"/></td>
</tr>
<tr>
<td height="64" align="center" background="images/thumbs-text-holder.jpg" class="planscopy" style="background-repeat:no-repeat"><table width="151" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="104"><span class="planscopy" style="background-repeat:no-repeat">Ground Floor - Dimensions</span></td>
<td width="47" align="right"><img src="images/pdf.png" width="48" height="51"/></td>
</tr>
</table></td>
</tr>
</table></td>
</div>
<script type="text/javascript">
$('#gallery').photobox('a', { thumbs: true }, imageLoaded);
function imageLoaded() {
console.log('image has been loaded...');
}
I would like the pdf.png image not to appear in the gallery, just to be a link to the document. Is there maybe a way to exclude a div id within a div?
Any help would be greatly appreciated.

try to give the A-Element ( PDF ) a class like "exclude" and try this JS-Code:
<td width="47" align="right"><a class="exclude" href="docs/Ground Floor Plan - Dimensions.pdf" target="_blank"><img src="images/pdf.png" width="48" height="51"/></a></td>
<script type="text/javascript">
$('#gallery').photobox('a:not(.exclude)', { thumbs: true }, imageLoaded);
function imageLoaded() {
console.log('image has been loaded...');
}
</script>

$("#gallery").photobox("a:not(:has([src$='pdf.png']))', { thumbs: true }, imageLoaded);
will work.(Demo for selector: http://jsfiddle.net/pUkz2/)
Note that the above selector is slower than if you add the class pdf to the a and use
$("#gallery").photobox("a:not(.pdf)', { thumbs: true }, imageLoaded);
I did a performance test: http://jsperf.com/pukz2

How to display text using if else

So, now I just type in this. Initially, I was going for the iframe target but I had the target on the picture already. What I wanna do is when I click on the image, the description will come out on the second td iframe. How do I link the function to the iframe( the 1st 1)
<script>
function myFunction(){
var resultBox = document.getElementById("scarf1");
if(resultBox == "scarf1.jpg"){ // <= you can put your condition here
resultBox.innerHTML="A soft brushed cashmere scarf featuring the iconic check. The scarf is made in Scotland at a mill with a long heritage in producing cashmere.To create a subtle lustre and soft texture, the cashmere is washed in spring water, then woven on traditional looms and brushed with natural teasels.Measuring 168 x 30cm/66.1 x 11.8in, the design is hand-finished with fringing.";
}</script>
<table>

Updated
It's hard to know what are you trying to do, however it seems your want put html when particular image is found..
HTML
<img alt="HERITAGE CHECK CASHMERE SCARF" onclick="myFunction('scarf1.jpg')"
JS
function myFunction(imgVal){
var resultBox = document.getElementById("resultBox");
// here is the id of result element instead ---^--- of resultBox
if(imgVal == "scarf1.jpg"){ // <= you can put your condition here
resultBox.innerHTML="A soft brushed cashmere....... ";
}
}

<!DOCTYPE html>
<html>
<head>
<script>
function myFunction(text) {
document.getElementById("demo").innerHTML = text;
}
</script>
</head>
<body>
<p>Click the button to trigger a function.</p>
<button onclick="myFunction(/* What you need to check */ ? 'Text 1' : 'Text 2')">Click me</button>
<p id="demo"></p>
</body>
</html>

Here you go:
JS:
function myFunction()
{
i=true; // i is true
if (i) // Check if i is true.
{
document.getElementById("demo").innerHTML="i is true"; // Event to do if i is true
}
else // else if i is not the condition above (true)
{
document.getElementById("demo").innerHTML="i is false";
/*
*Event to do if i is not the condition above
*/
}
}

here is something that you can test:
Not the best code, but you can copy paste this into the w3schools editor and you should be able to see it in action.
<!DOCTYPE html>
<html>
<head>
<script>
function myFunction()
{
if(document.getElementById("demo").innerHTML == "Hello World") {
document.getElementById("demo").innerHTML="Click Me";
} else {
document.getElementById("demo").innerHTML="Hello World";
}
}
</script>
</head>
<body>
<p>Click the button to trigger a function.</p>
<button onclick="myFunction()">Click me</button>

Multiple IP Camera Feeds On Same Webpage

I have 2 IP Cameras that have a internal server page (i.e. http:\192.168.1.10\video.html). This page receives jpeg images from the camera and auto-refreshes (loads) using javascript.
Source code from the video.html
<html>
<head>
<title>ipCam - JPEG Video</title>

</script>
</head>
<body>
<img id='the_img' src='image.jpg' onload='loadImage()' onerror='loadImage()'>
<br><br>
<a href='.'>Home</a>
</body>
What I would like to do is build a custom site that has both live feeds in it. I would prefer not to use <iframe>. I would rather use Javascript or something of the sort.
I have a basic understanding of HTML but very little Javascript experience. I can obviously look at the code a get a good idea of what is going on, but this has stumped me!
Any help would be appreciated!

I would guess that you could create a new HTML page (just copy the video.html from one of the cameras) on a local webserver and modify the script to include the ID of the img element you are updating and the IP address of the camera you are grabbing the feed from...something like this (which is set to automatically update the images every 4 seconds) -- (disclaimer: air code, not tested)
Thanks #A.M.K. for fixing some stupid mistakes in my code:
<script type='text/javascript'>
function loadImage(imgID, address)
{
var now=new Date();
document.getElementById(imgID).src='http://' + address + '/image.jpg?'+now.getTime();
}
setInterval(function() {
loadImage("the_img_1", "192.168.0.1");
loadImage("the_img_2", "192.168.0.2");
}, 4000); //Interval to refresh at, in milliseconds
</script>
Then just setup another img tag to receive the image:
<body>
<img id='the_img_1' src='http://192.168.0.1/image.jpg'>
<br><br>
<img id='the_img_2' src='http://192.168.0.2/image.jpg'>
<a href='.'>Home</a>
</body>
Note that you have two img elements now, each with a unique id which is fed to the function along with the IP address of the camera.
That may not work exactly in your situation, but that should give you an idea of how to accomplish it...

Just put the following javascript in your page, changing the interval parameter to your like:
<script type='text/javascript'>
var interval = 5; //Interval in seconds, to retrieve images
setInterval(function loadImage() {
var now=new Date();
document.getElementById('the_img').src='image.jpg?'+now.getTime();
}, interval * 1000);
</script>
and in the html just insert the image wherever you want, like this:
<img id='the_img' src='image.jpg'>
