More progress on ShowPicture. I successfully converted HAM8 ILBM images to 24bit PNG. I also successfully converted an ILBM with 5bitplanes (32 colors) to an 8bit PNG image file.

My reasoning was that the picture datatype for IFF loads all the pixel data into the planar bitmap (bm). The bitmap, I believe, has bm->Planes[8] where each Plane is a pointer to a UBYTE array of bitplane data. Because there are 8 planes (8bit) ReadPixelArray can easily turn that into an 8bit chunky buffer as when loading an 8bit standard image (PNG, BMP, etc). Then the image can be saved as any supported image type!
