Copy Observation to iOS Photos

How do I download or copy the picture from my Observation?

Thank you.

(This is my first post; sorry if I posted it in the wrong place.)

I access the observation from my iPhone using the web page version, not the app. Then press on the photo in the observation and it gives the option of saving to your phone’s photo library.

Currently you can’t, but there is a feature request to add this ability: https://forum.inaturalist.org/t/allow-saving-photos-from-ios-app/20148. If you support this feature request, please vote for it.
