Dynamically add image to powerpoint openxml

I am creating power point 2007 files using the openxml. I am able to add slides, shapes, text and manipulate them to create custom reports. However, I can not find an example on how to dynamically load an image into my power points. In principle I imagine that it would involve adding the image as a resource and then adding a reference to that resource. Any example code would be great help.

Thank you.
