To enable low cost distribution of pictures from a mobile entity that incorporates digital camera functionality, the mobile entity (20) generates both a high resolution picture image (81) and a low resolution thumbnail (80). This thumbnail (80) is distributed via a mobile radio infrastructure to a service system (40) that then transfers the thumbnail to specified recipients (60). After viewing the thumbnail (80), each recipient (60) indicates to the service system (40) whether they wish to receive the high resolution image (81) and, if so, whether it is to be transferred immediately or at the next. The service system (40) effects transfer of the high resolution image (81) accordingly. In other embodiments, distribution of the high resolution image is effected independently of the service system.
