Thanks for the answer, I suspected something like that.

But that means that the image format on disk, being binary, is native only to 
one endianess and not the other, making startup or saving a image faster/slower 
depending on whether the conversion needs to be done, right ? Or is this 
automagically fixed with the first save ?
