Convert transparent PNG on import?

[Marty Knapp]

Is there a way to convert a transparent PNG graphic to non-transparent 
when importing? There are 2 bugs on Windows (Mac is OK) when printing 
transparent images (any image with transparency or any image given 
transparency via blendLevel or inks. They are bugs 14089 and 14256 - 
both confirmed. They happen when printing and when using the LC print to 
PDF feature.

At this point I'm limiting my users to importing only Jpegs or BMPs but 
that is pretty lame. I've also disabled the image fading control I have 
on my Windows version. Certainly I can tell users to not use transparent 
PNGs but you know someone will and if they do it may cause them a lot of 
grief.

Alternately, is there a way to detect if an imported PNG has 
transparency? If so, then I could disallow just those.

Thanks,
