HELP - Rewrite or Action, how to tell if it's a direct image call or html page image

Hi we are trying to come with a rule or action that will do an action or rule if an image is called by itself in the browser window. We have tried everything! Is there a way to distinguish whether or not the image is in an html document, or being called directly in the url bar?

We want to parse code on a page with an image, any time an image is called and it is not in an html page. Thanks! PLEASE email
me if you have a reply! ceo@netcolony.com
