[cp-patches] [patch] fix BE image issues

[Andreas Tobler]

Hi all,

according to the process I'm asked to send the patches here regarding cp :)

Attached a fixlet to bring Big Endian Machines into happiness with Image 
representation.

It took a while to get it, but I hope I have it right. The reason for 
then long time is a bit stupid, I always tested against the wrong 
library  :(

P.S, Sven, it is no rocket science, but stupid enough if I test against 
an old installed library .....

Regards,
Andreas
