How to display literature images using open ui capabilities?

Hello everybody,

does somebody know how to display an image from siebel literature using a physical renderer?

Background: Users should be able to upload images by themselves (e.g. via Admin - Document), which should get displayed on a view rendered by a physical renderer.

By using a business service we already managed to access the business component for those literature images, but we have no idea on how to display the image of a literature record in an <img> element.

Analysing other applets, which already show images from literature, we found the swemethod "GetImage" was used in the src-property of the <img> element. Unfortunately this method is not documented at all.
