A receiving device in the form of a mobile telephone (10) within a mobile network (12, 14, 16, 18) receives images from a server (18). The server (18) first determines the characteristics of the mobile telephone (10), such as receiver memory capacity, display size, receiver colour depth, receiver processor availability and receiver display resolution. The server 18 then selects a version of the image, to be sent to the mobile telephone (10), suitable for use by that style of mobile telephone (10). The server (18) als o determines the bandwidth of the channel to the mobile telephone (10), and ca n adjust the depth of colour, resolution, and frame rate in the signal sent to the mobile telephone (10) further to accommodate the bandwidth and any limitations in the mobile telephone (10).
