Linux Wallpaper Problem

Okay first of all, I’m new as f*** to Linux (it’s sick so far) so don’t use any Linux terms with me. Anyway, whenever I set a picture as my background in Mozilla Firefox, I go to my desktop and the bottom of the wallpaper is cut off, any ideas?
Note: I’m using the newest version of Linux Mint. (Elyssa)
Answer #1
There are different settings for the background display in the Display Properties box (Right click, desktop background or properties).
Some of them are Zoom, Fit to Screen, etc. Pick one that you like the best.
Answer #2
Lol, I know that, that’s not the problem. But I have a different wallpaper, so I’m not having that problem anymore. Thanks for the help, though.
