I use a remote desktop program called GoToMyPC. The iPad app is free as is the program you need to install on your PC, but the service you need to pay for. There are several remote desktop programs out there and you'll see plenty of recommendations and reviews of them in the Forum. From your iPad you can then completely control your PC and have your iPad completely mirror your PC screen - so you'd be able to display the pictures on your PC - controlled from your iPad and they'd show up on your iPad screen.
