Convert transparent PNG on import?

After I posted, it also occured to me that not all transparent images 
use white as the alphadata color. So without transparency, you might end 
up with a purple or orange image you didn't expect. Hadn't thought of 
that. So yeah, probably wouldn't work on a couple of levels.
