No longer a newbie, moving up!
I agree with Amolitor - the photos are exactly what you get trying to photograph prints made on textured paper using a light source that is close to the lens axis.
The second shot has not been set up properly with the sensor and subject planes not parallel, or would someone want to claim that the shutter blades are jamming?
If it was due to something on the sensor then wouldn't it be dark blob rather than white?
The idea that the light pattern would be some sort of watermark is almost laughable - who would use a watermark that does not identify them as the owner.
More muddled thinking from most of the responders than usual on this one.
Amolitor is also right in saying that the best approach is to reshoot, possibly using diffuse light if the OP does not have access to a proper lighting set up.
