Trouble with photo syncing between iPhone and iPad
Two options:

Using iCloud:
- On your iPhone go to Settings > iCloud > Storage &amp; Backup
- Turn iCloud Backup on and wait for it to back up completely
- If you've already used your iPad, on there go to Settings > General > Reset, tap Erase All Content and Settings
- When you're setting up the iPad, it will ask if you want to restore from an iCloud backup—just choose the iPhone backup

Using a computer with iTunes:
- Sync your iPhone with iTunes—this will also make a backup
- If you've already used your iPad, on there go to Settings > General > Reset, tap Erase All Content and Settings
- Connect your iPad to your computer and follow the steps in iTunes to restore from the iPhone backup
