<p>A source document (40), such as an internet web page, including link data (24), such as hypertext links, is retrieved and has its graphical data content removed. The link data items are associated with category data (38) which is then used to select output graphical data items (46) to be associated with those link data items. The output document (48) excluding the original graphical content but including at least identifiers for new graphical content associated with the link data items is output as an output document. The above processing may be performed by a proxy server (10) disposed between a source computer (4) for the source document and a client device (8) requesting that document, such as a client in the form of a mobile telephone or personal digital assistant.</p> |
