I know that the img file size changes do not increase in steps of one byte.
Well, your special case did not occur in my test data. 
Maybe that was bad luck, I try with some more tiles. 
I thought the change is meant to reduce the *.img size? Or do you think that it
is an error to have such spikes in the *.img?

Ciao,
