Sorry for having to delete your image, but jpgs look very pixelated in thumbnail size. That's why we prefer pngs for small-size files. Unfortunately, there's no way to change a file type after the image is already uploaded, so the only thing we can do is reupload it in a different format, which is why we prefer not to allow jpg format for such files in the first place.

I would also recommend going through Category:Images. All images on this wiki are neatly categorised by source, which makes finding already uploaded images much easier.
