Picture Help

To edit my digital pictures I use the Kodak Easyshare program that came with my camera. I can crop and change colors and do fun stuff. It works well and then I can very easily upload them to Kodak Gallery so I can share them with my friends and family. But I'm starting to have some problems with it. It loads slow and doesn't have all the features I would like. So what programs do you all use. Does anyone know of a good digital editing program?
