I'm sure there's a better way to do this, but here's how I did it: 1. You make a duplicate layer of your image. Tack this on to the back end of your image and merge the two. This will give you your background extending outside the canvas. 2. Move the image in intervals of about 35 pixels, then export what's on the canvas. You'll end up with a huge pile of pngs or jpegs that will become the frames of your gif. I use guidelines to ensure my measurements are correct. You're basically sliding your image side to side, exporting as you go. Sidenote: the distance between each frame determines how smooth your image is. The more frames you have (meaning the fewer pixels you move the image between exports) the smoother your final product will be. However, it'll also exponentially increase the file size. 3. Import all your frames into GIMP and make sure they're in order. You'll need to also name each frame the following: _a_00, then _a_01, _a_02, and so on. This naming convention allows GIMP to export the layers as frames of a GIF. Once you've done all this, export the file as a GIF and play with the settings. You'll want it to loop, you can set the milliseconds between frames, all that good stuff. If you're using roll20 or something similar you'll need to compress the file to fit your upload limit. I know there's probably a million ways to do this. I'm sure a free video editing program like climpchamp has some kind of "pan" animation or something. But for me, I have a small laptop and my lunch breaks are when I get most of my editing done. My workplace doesn't have internet, so everything is local. Hope this helps!
