I haven't seen it shared in my timeline yet, so here's Broadly's collection of stock photos of trans and non-binary people: https://broadlygenderphotos.vice.com/
The pictures avoid the usual clichés, are generic enough so they can be used for many different topics, and they are released with a #CreativeCommons license (CC BY-NC-ND 4.0).
