If you are asking whether you could use CSS to set the wiki's background instead of using the theme designer, then you could actually do that. No issues there, because the rendering engines in browsers don't look at the end bit of URL to determine the file type.

But you couldn't simply paste such link into an article or a forum post to embed the image without one of the above tricks. There was usually less of a need for that, because you could simply add the file normally with the appropriate editor function. For us it was actually useful for embedding user avatars.
