Modify the src attribute of images after jQuery load via AJAX

Here is a test page I am working on:
http://secure.bbdesign.com/shoperenowharton/country.htm

The big background images look like this:
<img class="rwdimage" data-rwdimage="ph_home_country_1.jpg" />

Then, this code populates the SRC attribute based on some Javascript Media Query logic:
$('div#homebg').children('img.rwdimage').each(function(){
	$(this).attr('src', 'imglo/'+$(this).attr('data-rwdimage'));
});

Open in new window


That part works great. However, there are also some images loaded via jQuery AJAX towards the bottom of the page (you would have to scroll down a bit to see them) that are not working. They are marked up the same way as the background image. Here is the script that handles them:
$('div#content').children('ul').children('li').children('img.rwdimage').each(function(){
	console.log('imglo/'+$(this).attr('data-rwdimage'));
	$(this).attr('src', 'imglo/'+$(this).attr('data-rwdimage'));
});

Open in new window


Note the console.log, if you view the console log you can see that the browser is picking up the "data-rwdimage" attribute and modifying it correctly. Yet, applying this value to the "src" attribute of the image does not work, as it does work on the non-AJAX loaded images.

I am guessing this has something to do with the AJAX-loaded elements, since that is the only way that they are different (unless I have made an error somewhere). However, since the script is seeing the "data-rwdimage" attribute, obviously it recognizes the page element in the DOM, why can I not update the SRC value?

Would appreciate any input.
Thank you!

It's actually setting the source attribute perfectly fine.
The problem is you have the class set as "rwdimage", which has height: 0 property on it.

The images are loading, they just have 0 height so you can't see them.
