No. No. NOO. NOOOOOOOOOOOO! YOU'RE AN ARTIST! DON'T USE GIMP! USE PHOTOSHOP! Please... please, GIMP SUCKS! Use photoshop. It is waaaay better for drawing and also, it's better as a program. But well, too bad, if you want to make real transparent stuff you'll need GIMP, cuz Photoshop uses the chameleon transparency which just uses the background color but isn't really transparent. So for War3 Skins and Cursors and such you'll need GIMP. But only for that. It's such shit... poor mickey mouse gimp, when you minimaze it it closes, also I removed my tools menu by mistake and there's no way to return it
And many other stuff. Gimp sucks. Use photoshop... oh btw, you should join the cursor contest! Please! You can win it! You're amazing at pixel art... just think of a good idea. That's ALL you need, cuz you're good at the other thing - drawing it
I'll tell you how to make the stuff transparent in GIMP... just join :\
