Aviary is a free in browser program that allows you to import/export and has a lot of the tools PhotoShop has. You can also try GIMP which is free and downloadable
I had a trial of Adobe Photoshop and loved the preset grid to crop my photos in 5x7 size. Unfortunately I could not afford the program and I am trying to find one on cnet that is free but that has this perk to it. Any suggestions?
