I often need to move iPad screenshots from my iPad to my computer so I can edit or use them in my training materials. For this I use the app called PhotoSync ($1.99). PhotoSync connects to a free companion program installed on your computer. With this program and the app active, you can wirelessly send photos and videos between the devices. You can also transfer photos/videos between two iOS devices, such as two iPads or an iPhone or iPad. Highly recommended.
