You can also jailbreak the iPad2 first, and then use 91 Mobile Assistant to connect. After opening the Mobile Assistant, you will see Media and Entertainment on the screen, and Picture Management on the right row. This will allow you to see the pictures in iPad2. Just select which one you want to delete.
