How to get an access to an image in the Background View?

Hello,

I would like to retrieve information about image placed in a background view of a sheet. Manually I can add pictures by the Insert / Picture command. But when I try to use the CATIDftView::GetComponents method to retrieve the pictures there is not object containing link to the picture. What is the proper way to find images inserted in the background views of sheets?

Thank you,

Ivan
