### 1/5 — 🤔

*2024-12-02*

There is no image added There is no button to add photos Something strange, unfortunately

**Developer response:** Hello,
The app will only show photos in your library that contain depth data (typically, photos taken in Portrait mode). 

If you do not have any depth photos in your library, then no images will show up when you press the “load photo” button - this is expected behavior. 

Please reach out to support if you have any questions: contact@heliographe.net
