[Plugin: NextGEN Gallery] Displaying thumbnails – get_children type function?

Hi

I’m not sure if this is a complicated request or not.

I have a wordpress page which shows the titles of the latest posts. What I want to do is display a thumbnail next to these titles if the post contains an image or gallery.

One solution is to use the custom_fields when adding the post but I want to run this with WordPress MU and hence want it as user friendly as possible.

What I think should be possible is to see if a post contains an image/gallery and if it does then to display this image as a thumbnail. Is there a variable/function for nextgen similar to http://codex.wordpress.org/Function_Reference/get_children which returns if a post contains an attachement.

This is effectively want I want to do but using NextGen http://wordpress.org/support/topic/195811?replies=21

Any help would be great.

Cheers
