Handling collections of items when single item in schema?

I am writing a job board, and trying to use schema.org schemas in my data
model. I notice for Place that I have the property "photo", which
supersedes "photos" in the schema. How should I handle having multiple
photos for a Place? My question is more general than this particular
instance - I see a few other situations where a schema specifies a single
object as the Expected Type, and I need to use a collection of objects.

Thank you.
