Sorry for my lack of technical explanation - but every so often my photos have this annoying screwhead type image (can be one or many) showing. If you enalrge the pic below you will see what I mean.
I have checked for dust on the sensor, but all is clean - the images dont always appear in the same place.
Has anyone any idea why they keep appearing ?
