Are w3w address stickers added to the image metadata of the photo file or are they otherwise associated with the photo? Do the stickers show up for anyone viewing a stickered photo or only if the photo is viewed in the w3w app?

It appears that w3w-tagged photos under iOS/macOS carry the tag embedded with the photo file. A test photo I made at my desk at home shows in the Photos app with the tag which, when hovered/clicked-on shows an 'Explore' tab that, when clicked, brings up a w3w-supplied map view. Very cool and useful. 

Hey @Jim Salmons22 :) Thanks for your question!

-If you choose the 'Photo mode' option in ‘Settings’ in the app, you should be able to click a new photo/choose an existing one and add the what3words address sticker onto it. 

-This pulls the location info (Lat/long) from the image's metadata and converts it into a what3words address.

-To clarify: the what3words address is not stored in the metadata of images, but generated using the lat/long info that is stored in the metadata. 

- Also, if you import an image into the app, refine the location (so the what3words is different from the auto-generated one) and then press save, the metadata (lat/long info) will be updated with the new location you've tagged on to it. 

I hope this helps, and feel free to revert with any other questions if needed! 

Best,
