smart collection of image files linked to InDesign documents?

I would like to create a Smart Collection that finds all of the image files linked to InDesign documents in a specific folder.
I am the yearbook advisor at school and I need to easily find all of the images that have been placed so that we don't reuse images by mistake.

I have no scripting experience, so I can't create something myself, and I haven't been able to find anything that does such a thing.

Many yearbook design software programs do offer something like this - indicating that an image has been used previously.

I guess it would need to look at the metadata of the InDesign Files for the Linked Files and then pit all of the files found there into a Smart Collection.  Ideally, I would be able to further limit it by file type. ANd to not include Master pages if so desired (although that would just be a bonus!)

I greatly appreciate any assistance anyone can give.

Thanks!
