A search engine at a service provider is configured to identify commercial suppliers in response to a keyword specified by a user. Keywords are received and searches are performed on an index database to identify displayable text items. Images are stored in the form of commercially relevant graphical images such as logos. A logo is linked to each item of displayable text and an output list is produced in which each text item includes a displayable graphical image. The system may store different image formats to allow the graphical images to be displayed on a variety of platforms.
