We recently published Obscura, a new picture safe for Android. Obscura uses OI Safe to encrypt images, similar to how you encrypt your private notes in OI Notepad through OI Safe. Obscura uses the same master key and password as OI Safe. Therefore it is important that you back up the master key of OI Safe by entering OI Safe and pressing menu > more > backup. Otherwise you will not be able to recover your photos after a phone reset.

The free trial version is limited to 10 encrypted images. You can upgrade to the full version by buying a license from Android Market or from OpenIntents.biz.
