I have a bunch of thumbnails which I am loading with a style of visibility: hidden; so that they all maintain their correct layouts. Once the page is fully load
visibility: hidden;
Add a few calls to the chain like this:
$('.littleme').css('visibility','visible').hide().fadeIn('slow');
This will change it to display:none for 1 frame before fading in, occupying the area again.
display:none
