Answer 1

There appears to be a bug in iOS 5.0 which makes this tricky. You have to enable mirroring from the running task bar (scrolling all the way the left before a second screen is detected via the API. I've posted details in my question here: How to use iOS 5+ AirPlay for a second screen

Answer 2

You can write the app to handle 2 UIScreens using Airplay and an Apple TV then set a seperate root view controller for both the TV UIScreen and for the iPad UIScreen. Then display the image or slideshow on the TV's view controller and run that from the events of you iPads view controller!

AMENDED AFTER CLIFS COMMENT:

So firstly in your app delegate in didFinishLaunchingWithOptions or didFinishLaunching setup a notification to receive the screen did connect.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenDidConnect:) name:UIScreenDidConnectNotification object:nil];

Then you need to keep a reference to your separate window and push controllers to it as you would any other window.

- (void) myScreenInit:(UIScreen *)connectedScreen:(UIViewController*)mynewViewController
{    
    //Intitialise TV Screen
   if(!windowTV)
    {
        CGRect frame = connectedScreen.bounds;
        windowTV = [[UIWindow alloc] initWithFrame:frame];
        windowTV.backgroundColor = [UIColor clearColor];
       [windowTV setScreen:connectedScreen];
        windowTV.hidden = NO;
    }

    UIViewController* release = windowTV.rootViewController;
    windowTV.rootViewController = mynewViewController;
    [release removeFromParentViewController];
    [release release];
}

- (void)setTvController:(UIViewController*)mynewViewController
{     
    UIViewController* release = windowTV.rootViewController;
    windowTV.rootViewController = mynewViewController;
    [release removeFromParentViewController];
    [release release];
}

- (void)screenDidConnect:(NSNotification *)notification {
     [self myScreenInit:[notification object]];
}
