Ive heard of photoscape but never used it myself. lots of people like GIMP ive used and dont like it. i think its because its to simple. im use to using photoshop in my computer classes at school so thats what i like to use. you can get a 30 day trial off the adobe site, all you have to do is make a account.
Photoscape was on my computer so I have been using it. I havent used photoshop before
