The latest AARP Bulletin lists free online photo editing through citrify.com "where your uploaded photos can be tweaked with nifty effects like teeth-whitening and wrinkle-removing."

At pixorial.com you can get "free video online editing and up to 10 gigabytes of free storage."

I looked at what Citrify.com says they can do and, while I haven't tried it, it looks impressive. Certainly worth looking at, especially if you don't already have Photoshop.
