How to get saved images in Elgg

I'm saving an entity object of type entity and subtype album. When saving the album, I also save it with image files who's $ownerGUID = $album-> GUID. They get uploaded OK. The problem I'm now having is when it comes to retrieving the images. How can I go about listing all the images that belong to a particular album? Thank you all in advance. Elgg 2.X
