An asset is nothing more than a representation of an URL to some kind of image or style sheet. When asked to return it's content it will employ the asset service to do so. You should create an engine service that displays the image data with content-type image/* and call it from your page (much like the asset service used to deliver the asset with a given path). I wouldn't pass it the raw image data though but an object identifier which the service then uses to retrieve the object. Have a look here http://svn.apache.org/viewvc/tapestry/tapestry4/trunk/tapestry-archetype/src/main/resources/archetype-resources/src/main/java/services/RoundedCornerService.java?view=markup for an example of a service that generates an image and writes it to the output stream.
