All you need to post is your map link, but a link to the original image you found online would be greatly appreciated
(you'll also get priority if the original image is high quality, since that makes my job really easy).
You don't have to be sure if you have any issues, either; I can just give it a quick check for general quality/rankability.
If I don't find anything particularly wrong, I'll let you know (probably via PM).

I don't find new backgrounds, I just improve/fix/edit existing images.
