Dynax 7D or 5D ? Here i'm using a 5D camera.

Not from a RAW. Let's me explain :

In Camera interface, we have used the .thm file witch embeded a poor quality 
thumbnail. Why ? To limit the data transfert between the computer and the 
camera.

But i'm agree with you. The thumbs from .THM file are not really suitable. I 
can reproduce it here.

yes, but now need to do it. RAW files (MRW for minolta) embed an high qulity 
preview (640x480 JPG) witch is used to display picture on TV for example : 
the camera do not decode RAW image data, it's too long.

no, it's hardcoded.

Hum, it can be dangerous. actually this file type are drived in separate way.

thumb quality problem in camera interface.
