Duo Picture Frame is a gesture based image viewer that supports very high-res pictures, and allows zooming to reveal all the original picture details.
It's free, with no ads or in-app purchases, and no user tracking of any kind.

Pinch zoom or tap + drag on kitkat to zoom in and out.
Scroll (pan) the zoomed image with your finger.
Double tap to fit the picture to the screen (first double tap fits both dimensions to view the entire picture, second double tap fits just one dimension).

Use Picture Frame to open images from other applications (like QuickOffice or a file manager) or you can open an image directly from the app itself.

Supported image sources include:
- http and https (that's why we require the internet permission)
- intents (data streams coming from other apps)
- files

You can save the image to the Download or Pictures directory (useful when the image was opened from another app that doesn't include any save or export option).

Unlike most other image viewers, there's a progress indicator during the loading of large files so let you know that the app is working and not frozen.
