I use Gimp, but I don't recommend it. It's only for the 1337. Seriously, I really wouldn't recommend it only because I like it. Too many hate it.

I did some messing around with MS Paint on Sunday, and got some alright results for my first try. But as other have pointed out it gets tedious. For me it got tedious at about the third 32x32 sprite. I really, really don't like pixelling, but I'm the only one who can do it for me, so I'll have to suffer through. Attached are the three frames I did for one sprite, and here is some code I made to look at how it animates

1#include <allegro.h>
2 
3BITMAP* buffer;
4 
5BITMAP* Hero;
6 
7 
8 
9int Frames;
10 
11void Draw_Stuff(){
12     clear_to_color(buffer, makecol(0, 0, 0));
13     
14     if(Frames == 1){
15               masked_blit(Hero, buffer, 32, 0, 100, 100, 32, 32);
16     }
17     if(Frames == 2){
18               masked_blit(Hero, buffer, 0, 0, 100, 100, 32, 32);
19     }     
20     if(Frames == 3){
21               masked_blit(Hero, buffer, 32, 0, 100, 100, 32, 32);
22     }
23     if(Frames == 2){
24               masked_blit(Hero, buffer, 64, 0, 100, 100, 32, 32);
25     }
26     blit(buffer, screen, 0, 0, 0, 0, 640, 480);
27     
28}
29

34int main(){
35 
36    allegro_init();
37    install_keyboard();
38    set_color_depth(16);
39    set_gfx_mode( GFX_AUTODETECT, 640, 480, 0, 0);
40    
41    Frames = 1;
42    
43    buffer = create_bitmap(640, 480);
44    Hero = load_bitmap( "Characters/Hero.bmp", NULL);
45    
46    while(!key[KEY_ESC]){
47                         
48                         Frames++;
49                         if(Frames > 4) Frames = 1;
50                         
51                         Draw_Stuff();
52                         
53                         rest(100);
54    }
55}
56END_OF_MAIN()

For some reason the pixels from the previous frame are still visible when the next frame is drawn, despite the clear_to_color(), and I don't understand this. It's also a crappy-looking thing, but I understand that I need practice. Note: the code looks for the Hero bitmap in a file named Characters, just saying that so no one says it won't load because they didn't look at the code

EDIT: Crap, there's some attached code as well, but it isn't the right code, and I can't seem to remove it.

Well at first you could try draw_sprite. Then you should see whether there are some artifacts in the sprite itself - ussualy at the edges if the sprite. Sometimes when using tools which generate smooth lines (antialiased) magic pink gets other mixed with some alpha pixels and when saved produces different color.

Gimp and Photoshop are great for what they are made for: photo editing. Pixeling is something completely different and they aren't geared toward that, so there are more efficient tools I'd look at before resorting to either of those.

'So you want to be a pixel artist?' is another good tutorial about drawing. It's mirrored all over the place and half of them are down most of the time. Just Google for it...
