Some of the Jpegs were giveways - quality 7,8, etc. I only work at quality=10 or higher. I suspect if I did the test where all the images were q=10 it'd be pretty rare that anyone would perform much better than 50/50/random.

Still - I hope the test gets people thinking! :) Everyone talks about how bad lossy compression is but if you have trouble telling 'em apart in a constructed side-by-side test think how little it must matter to "joe average" when he doesn't have a lossless image to compare against.
