screen mirroring question

I want to show pictures on my TV from an iPad2. What I want to do is to manually flip through the pictures versus running a slideshow which has a fixed duration for the pictures. When the photo app is open and you can manually change pics it is in a 4:3 format on the TV. When I run a slide show it goes to full screen on the TV. Is there a way to have the pics full screen when changing them manually or another app that will do what I want?
