The Unofficial User Guide
Do you wish to look into tutorials but are stuck with a dial-up connection? Do you prefer reading hard-copies to staring at a computer screen? Or do you simply want an easy path of tutorials to follow rather than finding each one?
Here is an unofficial collection of 12 tutorials on using Paint.NET for both creating images from scratch and photo-editing. I ask that you thank the individual authors credited inside the tutorial, rather than me, for this. As I simply put it together. And yes, I have permission.
