I have a client site that requires a random background image. I figured that custom-background would have something similar to custom-header for randomizing which image is selected, but alas it does not seem to be the case.
Does anyone have experience doing this, or know what direction would be best to extend custom-background? Or would the better approach be to ignore custom-background and create my own background theme support (I severely frown upon this method, but 'the easy route' is always there).
