Edit text without affecting content in the column

I want to change the text in the column without affecting the image. How is it possible with Jquery? Is it possible to achieve only with Jquery without editing the html code?
See demo
$(".jsNoWrap").text("Change text");
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<td class="jsNoWrap jsalignleft">
<img alt="" class="img-thumbnail img-responsiveemblInline" src="https://i.imgur.com/3qzhIYP.jpg" width="65" style="max-width: 65px;">Change Me without affecting the image please</td>

JQuery is not the right tool to handle content without tag. Try JavaScript:
document.querySelector(".jsNoWrap").childNodes[2].textContent = "Change text";
fiddle (I replace td with a div for the demo)

Selecting first image in div and replacing image src

I am trying to find a way to select the first image found within a div and replace the image source. It specifically must be this method as the image doesn't have an ID (complicated to explain).
$('.promo-unit-site-logo-3').find('img:first').attr'('src', 'blank')')';
I have tried using the above code from googling around and clipping something together however I am by way of javascript a novice.
Any help appreciated!
Thanks,
John

see its working. you mistake in code.
var image = $('.promo-unit-site-logo-3').find('img:first').attr('src', 'blank');
console.log(image.attr('src'));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="promo-unit-site-logo-3">
<img src="http://placehold.it/280x210" title="first image">
<img src="http://placehold.it/30x20" title="Second image">
</div>

How to keep text on image slider?

Does anyone know how to keep the text on the image slider?
If the plugins is the solution they should not be heavy it should be easy to understand and implement.

You can add captions under each image using data-captionor in a span after the image.
You can add larger text using the title tag, for example:
<div class="MagicSlideshow">
<img src="example1.jpg" data-caption="Descriptive text can go here." title="Title here"/>
<img src="example2.jpg" data-caption="You can have one or two sets of text, or none at all." title="Another title"/>
<img src="example3.jpg" data-caption="You can also use HTML such as<b>bold</b>,<i>italic</i> and<a href='/magicslideshow/'>links</a>."/>
</div>
Plz refer this one.

Display img only when it has a title?

Basically in my ASP.NET MVC4 project I'm trying to have my validationmessages as tooltips (which gets displayed when hovered over a certain image).
Right now the error message is inserted into the image title - however I'd like to ONLY display the image when it has a title (when it doesn't have a title there is no error message).
How can I do this?
I don't suppose it is possible through CSS so a js/jquery solution would work too.
To clarify I need to check update the display as the title changes during runtime.
An initial check is not gonna do it.

Here is the pure CSS solution.
The CSS Code:
img{display:none;}
img[title]{display:block;}
Here is a WORKING DEMO
The HTML:
<img src="https://www.google.co.in/images/srpr/logo4w.png" />
<img src="https://www.google.co.in/images/srpr/logo4w.png" />
<img src="https://www.google.co.in/images/srpr/logo4w.png" title="" />
<img src="https://www.google.co.in/images/srpr/logo4w.png" />
<img src="https://www.google.co.in/images/srpr/logo4w.png" />
The CSS:
img{display:none;}
img[title]{display:block;}
Hope this is what you are looking for.

Only display images with a title?
$('img').filter(function(i, el){
return !$(el).prop('title');
// (empty/undefined titles evaluates as false)
}).hide();
Is this what you're asking for?
Perhaps this css selector is enough (will only work in modern browsers):
img:not([title])
{
display: none;
}

javascript examples display content boxes

I am trying to locate javascript code that, when I rollover an image, will make a box appear below the image and expand down (much like how a movie screen in a theater would roll from the ceiling to the floor). In that box, content would also appear, that I have previously added, that describes the image above. Already existing underneath the image I have a div with content in it...I would also like this div to be pushed down as the box described above expands down.
Any suggestions?
Thank you very much in advance!

Forgot the code that I am using...so what is happening here is that I have a picture, and below it, a small box, that when I rollover that small box it changes color. So, I want to add, when I scroll over that small box, not only does it still change color, but the new vertical expanding box appears below it. I have javascript in a *.js file that handles the already existing rollover effect but it's quite long and I wasn't sure if I should add that (it was create by Dreamweaver when I created a rollover image).
<div class="images">
<figure class="images">
<img src="../images/Flower2.jpg" width="300" height="199" alt="Life">
</figure>
<figcaption class="content"><a class="typeB" href="#" onmouseout="MM_swapImgRestore()" onmouseover="MM_swapImage('Image3','','../graphics/life2.jpg',4)"><img src="../graphics/life1.jpg" width="300" height="25" id="Image3" /></a>
</figcaption>
</div>

You don't give much information in your question about your current setup, but assuming that you have your HTML set out something like this:
<div>
<img id="tux" src="http://upload.wikimedia.org/wikipedia/commons/1/1c/Crystal_128_penguin.png" />
<div id="tux_desc" class="imgDesc" style="display: none">
<p>A cute penguin!</p>
</div>
</div>
<div>
<p>This text is part of the normal document flow</p>
</div>
Then you can use the following JavaScript (which makes use of jQuery):
$('#tux').hover(
function() {
$('#tux_desc').slideDown();
},
function() {
$('#tux_desc').slideUp();
});
You can see it working here: http://jsfiddle.net/wbAxm/1

something like this ought to to do it as long as the div to expand is directly after the image in the mark-up:
$(".class_for_images").on("mouseenter mouseleave", function() {
var content = $(this).next();
if (content.is(":visible")) {
content.slideUp();
} else {
content.slideDown();
}
});
If you want more than this, or it doesn't work, you'll need to post some code so that we can provide more detailed answers...
