It looks like MS changed the edit photo function for cropping and resizing. Apparently, the app now overwrites the original photos. I learned this the hard way today, and thought that it had the same 8.0 behavior. Nope. After I pressed save, there was no going back to the full-resolution photo. I really liked the old WP8.0 where the changes are made on another copy, and the original copy is NEVER touched. This made more logical sense to me because I like to play around with various editing, and once it's good, I manually delete the original picture. Here, it's no going back.
Most of the changes so far from MS have been puzzling and downright stupid.
