Follow these steps to delete photos in a Poster:
- On your smartphone, launch the Portable Ultra Short Throw Projector app.
- Tap on the wrench icon under Poster.
- Tap the wrench icon on the side of the Poster where the images you want to delete are saved under.
- Tap Delete all images.
- Tap OK then all the photos in the poster will be deleted.
