[Bug] Background randomization only occurs on screenshots not fanart

[iwubcode]

The background randomization does not seem to occur (or not in the same way) when Game Details > Game Background = "fanart" is chosen for the option and randomize background is on.

If the background type is "screenshot" the randomization works appropriately (re-entering the same game gives a different image)

I don't believe fanart can have more than one value

[iwubcode]

I think it should be able to. At least I have multiple backgrounds visible in gameOS's media section

They are listed as "screenshot" but I entered them as backgrounds:

  art/wii/backgrounds/Mario Kart Wii-02.jpg
