Paint.net, Artweaver, the GIMP, Pixia, Pixen, and Seashore are designed primarily to *create new* artwork.
Helicon, Photobie, Photoscape, and Photo toolkit are designed to *edit existing* artwork and photos.
Picasa, Irfanview, and XnView are designed to *view* images. They only have limited editing capability.
I recommend Paint.net for general use, the GIMP for advanced use, Pixen for Mac, Pixia for creating art, Photoscape for editing pictures, and Irfanview for viewing images.
