Would require volunteers for a lot of grunt labor, potentially. Even setting aside pulling thumbnails (can be half automated and then corrections issued for any that are uninformative) I would ideally want to add species tags. On the bright side, the basic info is all part of the file name. Series, episode, gender, cause. Don't know what it would take, really, as I'm not the one who assembled what you're seeing.
Glad it's pleasant to browse, none-the-less, and I'm sure recommendations on improvements would be well-received.
