When you usually open a "My drawings" section you expect some thumbnails, which doesn't happen on my page. Slows things down.... and I'm too lazy to make cute thumbnails :) I wouldn't use automatic thumbnailing... I'd have to go over each picture and rescale it, re...focus it. Maybe some other time.
But for now I just added meaningful names, yeeees, and I think that somehow solves the problem; it's kind of a middle way...
Besides, the images load so fast you won't have any trouble at all...
