At this moment I think I'm aligning with John Bowler, therefore no 
keyword, no compression. KISS

Problem is of course what to do with that thumbnail that can be either 
JPEG or two types of TIFF. For us a PNG thumbnail would of course make 
most sense, but that will likely break a lot of standardization.
