I made a GIF image of Florimel's two avatars so it would show them each in a continuous loop. It's not too hard to do so I can set that up for anyone who wants one.
I save each image as a GIF using a free program I downloaded called Giffy that converts the images with little loss of resolution. Then I use another free program called Unfreeze to put the images together in a loop. I can set how long it shows each image. There's a limit to how many images you can loop, especially if the file size of each image is large. I would be able to create a GIF of any size but you wouldn't be able to upload it here. If the file size is too large, the images don't rotate so you only see one.
