Your suggestion is along the same line as the suggestions given by Jan 
and Terry, which were all extremely helpful. Indeed, I went the way of 
setting imageData and alphaData, and that works quite well. One little 
word of advice to others who need to implement this: set the alphaData 
BEFORE setting the imageData, otherwise for some reason the screen does 
not redraw properly using the new alphaData information...

Wow! Wonderful! Perhaps you could give me a few pointers? For instance: 
are your 'skin' files actually stacks? - it seems that this is the best 
way to go about saving all the image and metadata information in a 
single file... Also, how do you then change the file TYPE of the skin 
stack, and how do you associate a custom file icon with that icon type 
on the Mac?

Once again, many thanks for all your suggestions!

Kind Regards,
