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 ) also determines the bandwidth of the channel to the mobile telephone ( 10 ), and can 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 ).
