This is a little OT, but the camera has been used to take pictures of bikes so maybe this is on topic.
Dot has a Sony DSC-P200 camera. A couple of months back spots appeared on images taken with it. Like this [Tree branches at the bottom are supposed to be there; the things at the top are not]:

I thought it was just gunk on the lens. So yesterday I finally stopped by a photography place and got the cleaning fluid and cloths. No change.
Any of you have an idea of what that might be?
