Jason, - Do you know in what order the images are loaded in to the browser? Just wondering, 'cause the images in the database are listed by ID (presumably in the order in which they are uploaded) but in the page itself they are presented in the reverse order, i.e. the first listed in the database is the last one of the thumbnails. This doesn't have anything to do with the problem, but was just curious.
Lyn, at the moment I seem to be getting good broadband speeds, and the test2.php is reloading properly 9 times out of 10 approx.
All the best!
PS I get the page loading consistently when I close and then reopen the browser, the only problem being that some of the images (a small minority) are still offset to the left.
