Gif Editor

Anyone knows a good gif editor/marker?
because i have one, but it just can open one frame per time, and with a image sequesce of 300 pictures, it is insanely painful, so anyone knows a gif creator/editor with “open image sequence” or open multiple images option, oh and with comments adder?

EDIT: Please, im needing it…

Umm unfortunately I have stumbled across a good, free Gif creator, but no editing gif applications. If you have tried searching on Google, you night find something more on some other search engines. Not like i’m trying to sound patronizing.

The Gimp is free and can make animated gifs.

ohhhhhhhh, S***!!
I have GIMP and i never noticed it. xD
