Well, probably the photo is supposed to be taken with the Hangover app in the first place. I don&#x27;t know app development,  but does an app that accesses the camera _have_ to store the photo alongside photos taken with the normal camera app?<p>My impression was: group of friends are in vegas having a &quot;Hangover (the movie)&quot; style night and agree to only take photos with this app. That way, come the morning they can all review them, but only when they&#x27;re all together.<p>Obviously, if they take photos with their normal camera, or if all apps have to save photos to the filesystem and can be seen by the built in photogallery app, this doesn&#x27;t work. Maybe the app uploads them to the Hangover site and then automatically deletes them from the phone?
