Board Thread:Support Requests - Designing Your Wiki/@comment-38998497-20191127204700

The main issue I have is that I want to make a pre-existing picture I made the background image for both the main page and for any articles on my wiki. I've seen on other wikis they have what look to be either JPGs or PNGs as the background for those pages, but I'm not sure what I'm doing wrong: theme designer on the admin dashboard did nothing, I tried setting it via uploading first as a picture and that didn't work, etc. I'll put the image I made below, I'm just not sure what to do.
