SPRITING DICTIONARY (and resources)

[Vipershark]

And now for the obligatory recommendation of not using MS Paint, as it usually won't help you that much. Instead, use a more advanced art & graphics editor, such as Graphics Gale (Clicky!). It's got more features and will ultimately allow you to get even the largest spriting jobs done.

Not exactly.

Most of us here use Paint, actually.
I still rock XP Paint daily, though a lot of us here use GraphicsGale as well. I have it for when I need to make gifs from sprites or images with transparency, but as far as basic image editing or spriting, Paint is my go-to option.

For most pixelart related needs, Paint does the job perfectly fine.
