Description of problem

My observations identified by URLs #2 and #3 were uploaded with the Android app, each with the same two photographs.

After reading the post identified by URL #1, I checked my observations identified by URLs #2 and #3 and found that, contrary to what that post shows, the photographs in the observations are not deduplicated between, or associated with, both observations.

(please provide a set of steps we can use to replicate the issue, and make as many as you need.)

I guess…

Step 1: Use the Android app to post two observations with the same photograph.

Step 2: On the iNaturalist website, view the metadata of each observation’s photograph.

Step 3: See that the photograph is not linked to both observations.

Did you duplicate first observation or just posted the second? Photos are linked only if you duplicate observation.

actually, i don’t think this is true in the Android app. i noted this in another post:

that said, i’m not sure if this is a bug or a design choice.

Sounds like a bug if size can change too.

I hadn’t realized that “duplicate” is a specific function of the software rather than merely uploading the photographs again. I see the “Duplicate” option now.

Automatically deduplicating/linking photographs separately uploaded to multiple observations would be nice, maybe for iNaturalist’s storage costs¹ as well as for users, but that’s more a feature request than a bug report.

(¹ although I don’t know whether iNaturalist’s storage may be doing deduplication already on its own)

… but did you actually try using that option in the Android app? did it actually do what you were expecting it to do?

I didn’t. Given your experience with that function, I would be more inclined to use the website to duplicate an observation.
