You should see some changes in look and functionality (for the better).
By the way, one thing I have recently found out and I am sure some of you have been affected by it, is images not displaying, and then to get them to display again you have to restart your browser. I was having a heck of a time trying to figure out what the heck was going wrong, but recently found the problem. Some images saved with photoshop7 include some extra bits of info in the image file....Then when my software copy's and resizes for thumbnails, that information is left in place, however, corrupt some how....Supposedly a photoshop7 problem, but I don't totally buy it....Long story short, there's a work around in place (some of you may have been affected as recently as today as a member uploaded one of these files), and all should be good.
Ok, I'm done rambling.
