Show friends only those photos that they should see.
No "accidental" swiping to the right/left revealing images not meant to be seen.
Fast and easy:
1. Select photos to show
2. Start the gallery and hand your phone to your friend
3. Done :)
You can even protect the gallery with a code. So that your friend cant close the gallery by himself.
