I'm a contributor to the Tablet Contributor Program. I can reproduce with your steps the same issue on my Flatfish tablet.

Offline discussed with Jerry, seems we are able to get correct image blob, but something went wrong when rendering it out. Need more investigation from gecko side and deassign myself.

I can reproduce on build 20140916012921.
I had experienced this bug since the beginning (shipment release). Now I have found that the same visual problem afflicts also PDFs, expecially when I try to view one in vertical orientation.
