Filter searches by number of photos or sound files attached

For example, if I am looking at unknowns (or any taxon), it would be handy to be able to filter for observations with:

  • 1 photo attached - I know I won’t have to ask the observer to separate anything, and can just start IDing unknowns
  • 2 or more photos attached - if I already have my “please separate” boilerplate on the clipboard, and can be ready to paste it when it applies

If it’s not on the filter, but can be a added to the URL, that would work too.
It’s currently possible for 0 photos using &photos=false , but it looks like it isn’t a available for 1 vs multiple.

It would also be handy for bulk annotating!

Adding Life Sage, Sex, Dead/Alive can go faster if I can filter to only look at observations with 1 media file (be it photo or audio), and then come back later to look at the ones with multiples.
