I found a desktop background online that I rather like and instead of saving the file to disk normally and then setting it as the background, I simply pressed "Set as Desktop Background" from the context menu, which is an option that apparently comes up in Firefox for likely-sized images.
Now I wish to use it in my Ubuntu partitions as well. Where is the image stored on the filesystem when I set it as the desktop background without explicitly saving it to disk?

When using Firefox in Windows, it's saved a couple of directories above your profile. More specifically, it's
C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Desktop Background.bmp
