Not finding image source properly despite giving the correct path in html

I'm stuck with a problem. I Have Worked on images before in html but there never seemed to be a problem. I'm partially working on a project and I am giving the right path to the folder but the image is just not showing up. All the images had the same problem. Here is my code Snippet:

My htdocs path is like this:
F:\xampp\htdocs\Main Files\UniLearn\UniLearn (with Options Panel)\img

Brother, i think the problem is in the paths, you have here 3 choices base on your HTML page location:-
if the .html file is in the same folder with the image your code should be like this:
<a href="page-profile.html" class="instructor-avatar">
<img src="saif.jpg" alt="">
</a>
(.html page beside saif.jpg)
if the .html file is in a folder contains the folder of the image your code should be like this:
<a href="page-profile.html" class="instructor-avatar">
<img src="UniLearn/UniLearn (with Options Panel)/img/saif1.jpg" alt="">
</a>
(.html page beside the folder UniLearn)
if the .html is in a different folder you need to jump up levels till you reach the nearest common folder and point to the image code should be like this:
<a href="page-profile.html" class="instructor-avatar">
<img src="../../UniLearn/UniLearn (with Options Panel)/img/saif2.jpg" alt="">
</a>
(.html is in a path two levels far from UniLearn)
-->(../..) Means go up two levels in the folder structure.
hope this helps

i think the problem is in your directory name spaces.
try to take picture from other directory then you will see what is the problem.

the problem is with the spacing. if you want to keep the naming (not recommended) and still use the image try this:
<img src="UniLearn/UniLearn%20(with%20Options%20Panel)/img/saif.jpg" alt="">

It is hard to tell with only this information.
Here's how to troubleshoot this:
First replace all spaces with %20 this is the way to url encode those characters.
If it still is a problem (normally browsers auto url encode), compare the URL you are using to access the website, the href in the base tag if there is one, and the url of the image. The browser will use those 3 together to figure out the final URL...
You can right click on the picture, and open in a new tab. It will allow you to rapidly see the URL that is used to point to the picture and allow you to make changes.
Also, since you are on a unix machine, the case is important. Make sure that all capitals should be present.

How to resize modal from bootstrap

I am new to modal pop-up from the bootstrap. I am currently using here a modal from the examples on w3schools. I want to insert my input form inside the modal. So when the user click the Upload File button, this modal will pop-up. Here is the photo: (Please take a look at this image)
As you can see, my problem here is the input fields are unorganized, I just want to resize the modal so the input fields would fit in. How can I achieve that? Your help will be highly appreciated. Here is my code:

Bootstrap Modal don't open in photo grid

I have a photo shuffle grid, with this grid I can select a few theme's and it shows only the pictures of that theme.
Now I want to do the following, when I click on a image I want a modal to open. The problem I have is the following:
The first image (with a modal in the back) opens without problems, but the other pictures (with modals) do not open probably, I see them (half) but I can't click on them.
This is my code:
HTML
<ul class="portfolio-sorting list-inline text-center">
<li>All</li>
<li>Heren</li>
<li>Dames</li>
<li>jongens</li>

</ul>

CSS and JS you can find on https://jsfiddle.net/hrpj3j9t/2/

1) Bad code provided on jsfiddle - unclear, modernizr in js code section
2)From my point of view the best way is to generate code you need with jquery. In imageSrc I mean the real path to image.
This the small example of concept:
Place modal at the top:
<body>
<div class="modal" id="modal">
<img id="modalImage" src = "" alt="image">
...
</div>
...
<div class="elementOfGrid" data-image="imageSrc">
</body>
in js:
$('elementOfGrid').click(function(){
$('#modal #modalImage').attr({"src":$(this).data("image")});
$('#modal').modal("show");
}
another variant instead of setting attribute you can generate the whole html and use it like this:
$('#modal').html('');
var htmlRow = '<div class="modalImage"><img src="imageSrc"></div>';
$('#modal').html(htmlRow);

Boostrap modal showing popup content on page before clicking on modal button

Trying to make this modal work on the checkout page here: http://designatwork.net/c3/checkout/ under the "Have a Physician Code? Enter your Physician Code" link at the top. When I put the modal code in, it shows the content that's supposed to be in the popup below the link that's supposed to open the popup. How do I get this to work properly?
<p>Don't have a Physician Code? <a data-toggle="modal" data-target="#physcode">Get one here!</a></p>
<!-- Physician Code Modal -->
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-body">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<p>AQ Skin Pro products are available exclusively through participating clinics and physicians offices. If you do not have an Exclusive Physician Code, click "generate a code" below.</p>
<button class="nm-simple-add-to-cart-button single_add_to_cart_button button alt" data-dismiss="modal" aria-label="Close">Generate a Code</button>
</div>
</div>
</div>

You need to wrap your modal content within the a <div class="modal fade"></div> and have the role="dialog" attribute to that wrapper as following :
The modal html goes like this:
<div class="modal fade" id="physcode" tabindex="-1" role="dialog" >
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">x</button>
<h4 class="modal-title">Physician Code</h4>
</div>
<div class="modal-body">
<p>AQ Skin Pro products are available exclusively through participating clinics and physicians offices. If you do not have an Exclusive Physician Code, click "generate a code" below.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
And the trigger element looks like this:
<p>Don't have a Physician Code?
<!-- Button trigger modal -->
<a data-toggle="modal" data-target="#physcode">Get one here!</a>
</p>

You need to wrap the entire thing in a modal div, also there you need to set the id of it to the element that the button uses. Try this code:
<p>Don't have a Physician Code? <a data-toggle="modal" data-target="#physcode">Get one here!</a></p>
<div class="modal" id="physcode">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">x</button>
<h4 class="modal-title">Physician Code</h4>
</div>
<div class="modal-body">
<p>AQ Skin Pro products are available exclusively through participating clinics and physicians offices. If you do not have an Exclusive Physician Code, click "generate a code" below.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
Or pulled directly from my website, I use jQuery to open the modal automatically, but a button still works to open it.
<div class="modal" id="modalLogin">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">x</button>
<h4 class="modal-title">Login</h4>
</div>
<div class="modal-body">
<form class="form-horizontal" id="formLogin" method="post" action="./index.php">
<fieldset>
<div class="form-group">
<label for="inputUsername" class="col-lg-2 control-label">Username</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="inputUsername" name="inputUsername" data-validation="alphanumeric length required" data-validation-allowing="-_" placeholder="User">
</div>
</div>
<div class="form-group">
<label for="inputPassword" class="col-lg-2 control-label">Password</label>
<div class="col-lg-10">
<input type="password" class="form-control" id="inputPassword" name="inputPassword" data-validation="strength required" data-validation-strength="3" placeholder="Password">
<span class="help-block">Forgot My Password</span>
</div>
</div>
</fieldset>
</form>
</div>
<div class="modal-footer">
<a type="button" href="./index.php" class="btn btn-default">Cancel</a>
<button type="submit" class="btn btn-default" form="formLogin">Login</button>
</div>
</div>
</div>
</div>

Bootstrap 3 submodals?

I've seen that a working twitter bootstrap sub modal plugin works for older versions of bootstrap but it's not been updated to v3 by the author it seems.
I did change the markup to align with v3 but it seems like the CSS/JS needs some extra 'hacking'. Has anyone found a workaround this or some other plugin that allows this feature that they could share? much appreciated
github https://github.com/jakiestfu/Bootstrap-SubModal
Fiddle: http://jsfiddle.net/chou_one/eS7us/3/
<!-- Sub-Modal -->
<div id="mySubModal" class="modal sub-modal hide" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-body">
<p class="center">Are you sure you want to close your account?<br />You won't be able to undo this.</p>
<hr />
<form class="form-horizontal" role="form">
<div class="form-group">
<label for="inputEmail1" class="col-lg-2 control-label">Email</label>
<div class="col-lg-10">

<button class="btn btn-danger" data-dismiss="submodal">Close Account</button>

</div>

If you don't nest the html structures of your modal and submodal it seems you don't need any additional code. Example: http://bootply.com/85842
<div class="container">
<div class="row">
<!-- Button trigger modal -->
<a data-toggle="modal" data-target="#myModal" class="btn btn-primary btn-lg">Launch demo modal</a>

I'm the author. Bootstrap Submodal is now for 3.x versions of bootstrap only. Hope you have enjoyed using it, sorry this is a late response!

I'm using this to control the 'z-index' for modal and 'modal-open' class for body.
NOTICE: don't add the submodal html code inside of the modal.
$ ->
$('.modal').on 'show.bs.modal', ->
$('.modal.in').css('zIndex', 0)
$('.modal').on 'hidden.bs.modal', ->
$('.modal.in').css('zIndex', '')
setTimeout (->
if $('.modal.in').length
// it seems it will remove the modal-open after 'hidden.bs.modal', so add a setTimeout
$('body').addClass('modal-open')
), 500
