Move Photos from iPhone to iPad
Use Image Capture to import the pictures to your computer.
In iTunes, connect and select your device, then in the Photos tab select the folder that you put the photos when you imported them.
Press Sync.


Once you've done this once, it become easier. You already have the folder set up in Image Capture and in iTunes, so all you have to do is…


Connect your iPhone (you can set up Image Capture to open automatically when you connect your iPhone in System Preferences).
Click Import.
Connect your iPad and click Sync.




Alternatively, you could purchase an iPad Camera Connection Kit, then use a USB cable to connect the iPhone directly to your iPad and use your iPad to import the photos.
