This is actually very easy on a PC.
Its just another drive in the windows file system.
Heres how to do it:
1) Plug the iPad into your PC, you do NOT need to synch it.
2) Find the "computer" icon on your desktop, open it
3) From there, find the name of your iPad's icon, open it
4) From there drill down to internal storage > DCIM
5) You will then see your JPG pictures, copy and paste to your computer
Also, you can do this with ANY digital camera, they all store
photos in there own DCIM folder.
Enjoy!
