SOME POINTERS:
Photos typically include their locations, so you can use locations as keywords too. You get more hits with shorter words, and fewer hits as you become increasingly specific with increasing numbers of keywords. It’s best to use singular rather than plural (eg “volcano” instead of “volcanoes”).
As some words are included in others (“salt” within “basalt,” for example) you might want to be more specific to avoid getting a bunch of irrelevant photos.
Or you can just scroll down and see the most recently added photos… Enjoy!
