I think there are three things that need to happen each time you get more 
content, at least two of which are asynchronous:

1. your ajax call to get content, asynchronous
2. when you place received HTML code into document, browser will start to 
render HTML, but without the images yet.  I believe that if you run the 
deferred command as suggested just after setting the HTML content into the 
panel, it will run when the HTML is fully rendered, but w/o any images in 
place
3. browser will start to load referenced images (from img tags src 
attributes) and other items with src, possibly in parallel with the 
rendering of the HTML

If you really don't want to start loading any new content until the HTML 
and images are fully loaded, then you would need some mechanism to know 
when all the images are complete.  You might actually want to still use a 
deferred command at this point, since the point in time where images are 
loaded is probably earlier than the point where they are actually rendered.

You can help out the process if you control the incoming HTML, by using 
height and width attributes in the img tags.  That way the placeholders 
will be sized immediately, and you wouldn't have to wait until they have 
loaded. Unfortunately, I believe that this gets in the way of "responsive 
design", since it prevents a max-width css rule from working correctly.
