if you've never used picnik.com, it's wonderful for photo editing. i am not the most computer-literate person and will probably never have the strength to attempt photoshop. it's completely frEE too! take a look around and try out all the fun stuff they have! there's some more tools accessible if you pay the annual fee of $20 some dollars. i've signed up for this, but you don't have to to get access to lots of the features.
try it out and let me know what you think!
