Pretty good pictures, in no time you'll have mastered the camera, producing pictures to make us drool.
I'll go along with the graphics editor, it's a tool you can't do without. I use Ulead PhotoImpact - it's as good as or better than Paintshop, and reviews put it at one of the eaiest to learn, and up there with the pros. The best part is that it's soooooo much cheaper

What camera are you using? If you let us know, somoene with the same one could give you more personalized tips.
