Hi Diana19,
It seems you are having trouble with photos after restoring from a backup. You may want to consider restarting the device first, and then resetting if that does not work. This article provides detailed instructions for Restarting, and Reseting:
Restart or reset your iPhone, iPad, or iPod touch - Apple Support
- Press and hold the Sleep/Wake button until the red slider appears.
- Drag the slider to turn your device completely off.
- After the device turns off, press and hold the Sleep/Wake button again until you see the Apple logo.
- You should reset your device as a last resort and only if you can't restart it.
- To reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.
Thank you for contributing to Apple Support Communities.
Take care,
