As far as I know there were no dedicated PR units in Greece at that time. It wasn't unusual, however, for other aircraft to be fitted with cameras - most British bombers of the time had the ability to carry at least one camera and, in the absence of dedicated PR units, would be used locally for PR purposes. I think you'll be lucky to find any pics - bear in mind that getting those photos to the UK would be challenging as Greece was progressively overtaken by the Axis.
