Set its data to NULL, and expected the gif to show up as cover art in Mobireader. Well. That is not the case. I wonder if MobiReader expects the thmb to be a certain size max and I can not test on a Cybook :-(. Is there anything else that might need to get set ?
On the Cybook only 201 seems to be used and if they do not exist that firstimage is automatically used as cover image. I do not now how the Mobireader works.
