I'm looking into possibly getting some sort of photo editing software. The thing is I have never used any and I don't have that much money. I don't need to do much with it, just make a couple signatures & avatars & possibly edit a few pics. I also won't be using it too much either, just once in a while. I need something that is really easy to use, I'm not too computer savvy. Do they have anything like what I need for under $100?
