Display photos from NSDocumentDirectory

I am developing this application on an iPad.

These codes for the Browse button allow the user to view photos from the iPad gallery.

- (IBAction) BrowsePhoto:(id)sender
{
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:imagePickerController];
[popover setPopoverContentSize:CGSizeMake(320,320)];
[popover presentPopoverFromRect:CGRectMake(200,200,-100,-100) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.popoverController = popover;
[imagePickerController  release];
}

When a photo is selected, it will be saved in the application using NSDocumentDirectory.

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)selectedImage editingInfo:(NSDictionary *)editingInfo 
{
[self.popoverController dismissPopoverAnimated:YES];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [paths objectAtIndex:0];
NSString *savedImagePath = [documentsDir stringByAppendingPathComponent:@"SavedImage.png"];
UIImage *image = imageView.image;
NSData *imageData = UIImagePNGRepresentation(image);
[imageData writeToFile:savedImagePath atomically:NO];
}

Now I have to enable the "Show" button on the first screen. When you click on the button, it will display the new view (modal view controller) and display all the photos in a thumbnail / tabular view from NSDocumentDirectory.

When a photo is selected, it will be deleted from NSDocumentDirectory.

How can i do this?
