I'm constructing a wiki for the upcoming DMC game (now I know that there is already a DMC wiki but since this is about the reboot, it should count as a seperate game and the wiki is suppose to be about the reboot) and I need help with the background image.

I'm trying to make the picture expand with no tile or anything. I just want it to be bigger and I don't know how to do that exactly. All I can do is put in Fix and Tiles and that's it. I've seen other wikis using an expanded image and wanted this wiki to have an expanded image too.
