Today I was looking into a few sources and I wanted to see some labs of their products. I got lucky with one source as they had a mass-spec test appear in their review page, but it was very difficult with the other sources.
I assume the "Submitted in courtesy of" fields are tracked in a database, so I think it should be easy to create such filters, they'd make navigating through the pictures (especially lab tests) much easier.

Thanks in advance
