If you want to add your background in Special:ThemeDesigner there's a file size limit like Rappy said.

But you can also use the following code in your Special:CSS to have one with a bigger size: /* better background */ body.mediawiki { background-image: url("url of the picture here") !important; background-size: cover; } A disadvantage of this background is the load time will be longer.

Hope this helps you!
