I wanted an avatar of Ulrich using Triangulate, and since I don't know how to do animated images, I was going to make a request. However, do I just need to post a picture of him using Triangulate or what?
What you are referring to is a GIF (Graphics Interchange Format) file. And if you want a GIF of that, you'll need a video clip of your desired timeframes. Then I or anyone else can take that video file and make a GIF out of it with avatar specs.
