You also have the option to send out an event to all CD serves telling them to clear image cache for a specific assetId.
To enable the event on the CD Server locate the following file \App_Config\Include\damforsitecore\DFS.Connect.config. Open it and find the tag events. By default the event name publish:dfsClearCache:remote will be commented out. Remove the commenting and enable this custom event.
