Do you still have the site on the previous web host so that maybe it could be compared to? I am only seeing 3 JavaScript files being requested and none are to do with the fade in of the images.
I even tried searching for 'entry-image' on the page for any inline JavaScript that might be touching on it but all I see being done is background colour (CSS) and the three image classes (HTML, elements).
Unfortunately I do not have it on the previous host no, I have it saved locally and it all loads fine...
NOTE: It SEEMS to load fine on mobile devices, but that may not be true as I haven't tested it.
