Good god, the term 'gif' isn't a program it's a file format, seriously, how do you people live with computer illitericy?
Sorry if that hurt. But you need to learn.
What makes you so high and mighty? This board is here for a reason, its for people who don't understand something to come and ask. What they don't need is people coming and making them feel bad about it. If people keep this up it will render this boar useless, as people will be afraid to ask.
I have seen this far too much lately, I'm sorry if I'm back seat modding, but it really really annoys me.
tutorial with gimp:
make a new picture: size 128/128 or bigger
draw something and open
Filter---> Animation ---> spinning globe
setting: set 40 frames, and from left to right
now, gimp create 40 new layers
preview: you can see the spinning head in a preview
Filter---> Animation---> Play Animation
you see it works, or not
close the animation window and save the picture with the 40 layers as
save as---> picture name.gif---> animated gif
look at your folder and upload you GIF on imageshack or elsewhere
