What are some useful graphic editing tools?

Title says it all, because I'm bored and would like to know what programs are good for editing textures, sprites, etc.

for making textures i'd recommend photoshop/gimp, because filters and layer control are super handy.

for making sprites they both also work, but you might be better off with graphicsgale or paint.net. most pixel artists i know are super happy with graphicsgale, it might not be perfect for doom style stuff though.

In addition to what jmickle said, feel free to make use of the "Graphic -> Color Remap" feature in SLADE3.

But better don't abuse it on everything, please. :)

I use GMImageEditor that I've gotten from Darsycho.
