[Chameleon] raster image showing up with 256 colors

[Eijnden, B. van den (Bart)]

PNG (many Kb's!).

But indeed quality of JPEG can sometimes be insufficient.

Best regards,
Bart

Hi,
I'm not sure, so others may have a better knowledges of this, but the 
JPEG can have less quality and may not support transparency.
