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).
