I tried uploading it to Faceplace.
It told me that I couldn't because it wasn't 120 pixels tall.
So, I had to put it into an online .gif editor. When I did that and saved it as a slightly larger format, it ceased to function.
So, I had to run it through the editor again, enlarge it, and save it as an MP4.
Then I could upload it to Faceplace.
