I have never gotten involved in this myself, but I believe the image is stored as binary information inside the actual GSM object.
You can not access the images directly in the GDL editor.
I believe you need to use the LP_XMLConverer tool to extract the images from the file.
It can also be used to re-create the object and embed the images in it.
