Well, actually, tons of them have non-standard dimensions. I routinely crop out edges, especially to show only the important details, and also to save space for display size and compression. With this Leatherhead GIF, I wanted to capture the look on his face, along with the rest of his head and Mikey's hand there. Leatherhead's head was moving a lot vertically, but not so much horizontally.

I actually don't mind if GIFs are vertical, since:
 * It's primarily just a layout issue on my GIFs pages, which use a custom layout of my own design using CSS inline-blocks (instead of the standard Wikia gallery grid).
 * It doesn't break standard Wikia gallery grids.
 * If embedded in an article, it can still be made to float to the right or left of text.
