Looking at the code one needs a library that can read any/more forma 
images as RGB data arrays,as it says in soure

if fltk is linked with csound, fltk depends on libjpeg and libtiff, so these should be available too, on OS X and Linux anyway

Looks promising; now we need a programmer who understands something about 
images, ie not

;) yes lets wait a bit...
i will put this in the issue tracker.

It is only interesting for importing of different image types, think. It
would make the use of these opcodes faster, because now i have to do some
bash converting beforehand.
For exporting i am fine with using just the PNG format.
