I just tested on my linux server, and it works.... So, let's modify the script sys.stdout.buffer.write( f.read() ) sys.stdout.flush() Now I have: malformed header from script. Bad header=ÿØÿà: show.py and it tells me Internal Server error :( I can't see the error messages (traceback) any idea to do so? Dorian

You have to flush sys.stdout before using sys.stdout.buffer, such that the unicode layer doesn't keep any unwritten data. So this should be: sys.stdout.flush() sys.stdout.buffer.write( f.read() ) Regards Antoine.

Now with the fix : All browsers shows a different thing, but not the image! http://ddclermont.homeip.net/misc/python/ If I save it to computer : * Windows image viewer won't read it * Irfanview can read it without problems Dorian PS : ça commence sérieusement à m'énerver
