Hey guys! I haven't contributed for a long time, but Pixel Dungeon keeps updating and new content such as images and gifs need to be added. I can't do it, however, because I have a lot of work around university. So I figured I could do a tutorial for those of you who want to add good-looking images and GIF's to the wiki. This was also brought to my attention by Ethaniel and EgotisticalMe.
So here's a tutorial for creating GIF's. But also know that I used a lot of the same techniques for creating nice looking .png files for the wiki.
I hope this is useful. Enjoy!
