I am quite impressed with the awesome photos in the Baker Illustrated Reference Collection (4 vols.). I am puzzled however about how to find certain photos from the Bible Facts tool. For example:
In The Baker Illustrated Bible Handbook we can find a photo of a papyrus scroll.

But when I search in the Bible Facts tool for 'scroll', I get hits from several other resources, but it does not include this particular photo above.

Does anybody know how photos in resources like these are tagged? I would think that resources containing many photographs become more accessible and useful when they would show up in the Bible Facts tool.
So, how can I easily find this photo without having to remember that I have seen it in this particular resource, somewhere in the chapter about Pastoral Epistles?
