Board Thread:Support Requests - Designing Your Wikia/@comment-28122555-20140531191253

So I occasionally use the Sims wikia and I see it has a mosaic background of sims going across in all of their pages at the top.

It's way too big to be a wordmark and it's definitely not the gradient background because it sticks at the top under the wordmark and bar etc when scrolling

How do I include this on my own wiki without any messy codes involved? Obviously with a different image, because my wiki isn't about Sims. I just want the thing and nothing else

I'm sorry if this confuses anyone, this is my first time using a wikia forum..
