Exactly.

OK with me.

Yes, the user can add these additional options.

Perhaps we can have one additional penguin from the "with image" demo in a 
png file instead of an .rgb.

Actually, scanned images (e.g. from microscopes) are usually in .tiff, so 
converting them into png and adding axes and label by gnuplot is an example 
of an application of png files.
