Q: Why does it say I've used 2gb of storage on photos but I have 0 photos

Hi albany56,
 

Thanks for participating in the Apple Support Communities.
 

If your iPhone says you're using 2gb of storage in the Photos app but you don't have photos in your camera roll (or the Years/Collections/Moments section), try checking the storage with iTunes using the steps in Check your storage on your iPhone, iPad, and iPod touch.
 

Also, if you have iCloud features like Photo Sharing or Photo Stream enabled, these features will use storage on your device. See iCloud Photo Sharing FAQ and My Photo Stream FAQ.
 

All the best.
