:::::Second, looking at the above image, the black square with a play button in it will not work; it looks tacky. If we do allow images in the WebM format, they would need to be images that are absolutely necessary to view the animation to understand the principle or point of a page. Few, if not no images need that.
:::::As for the GIF idea, the more extensions that we allow in the archives, the easier it is for duplicate images to hide. In cleaning out the GIFs, you won't believe how many unused and duplicate images I found. Also, if we were to convert just the sprites to GIF, that would take months to do and really isn't worth it (especially when it took me about a month and a half to convert and upload the APNG versions of the Emerald and Crystal sprites).
