The Warrior. The Black, and the White mage!
Are u you talking about programs? in that case there is a lot of programs to export your animations to GIF, aseprite, pyxeledit, graphicsgale etc etc .. if there is nothing weird in your sprites they should be accepted.
I can do that. But the last time I added a walking animation I got a revision needed... what's the best protect to use to make gifs for this site?
its going to look much better if you include the animations instead of the sprite sheet
