I see PICT (MacOS), PNG, Targa, PPM, and QuickTime (MacOS). I was hoping
for TIFF or JPEG since those are the ones I use most, but I think I can
get my images into PNG or PPM format.

I assume that POV can read all of the formats that it can write (except
QuickTime, of course)?

This looks like exactly what I need to get started. Thanks!!
