automatic reference to nodes that entities are connected to ?

Hi ! I'm not sure this question is specific to this module or if that's a more general question about how entities are working within drupal.

First, here's my basic setup:
- a content type "gallery" with some textfields and a "plup" selector to upload my images
- then i can edit my image individually (threw media module browser) to add each entity a short description
All is ok with those galleries.

Now when editing individual images (using media browser) i would like the admin to be able to see in witch gallery node this entity is used.
>> image X >> used in node Y

I've setup an entity reference field for my images entities, and what it does is that i can manually select the node my images are related to.
But is there a way for entity reference module to automatically detect what node my entities are related to ?
