Hmmm... the only issue with the code on the site at the moment is I don't believe it actually is loading the files, compared to the code that aceres posted.
Sad thing is I can't get the code to load the images before the others. The only thing I could suggest is that either some form of lazy loading is done on thumbnails previews themselves or you do the slightly nasty (is it nasty?, I think it's rather effective compared to some really nasty web techniques) of loading an image in a hidden div before the rest. But well, it is a tiny thing on the site. Shame that link prefetch has such bad browser support haha.
