As was pointed out when I submitted aviary.com a few months ago - this isn't nearly as powerful as Photoshop, though it has a good set of features. Photoshop is Photoshop because it is a dog of a program with more features than any casual user will ever need to use. I do understand why you mention Photoshop in your title, though, but something like "layer-based online image editor" works more precisely. That said - anybody who likes this might like Aviary.com. It's got more tools, though it seems to be slower to load, it hosts your images online, and it's got a very nice social hobbyist environment.
