Even though you have the nil check, it's still possible to leak memory. I think what is happening here is that you are calling alloc / init multiple times, but only releasing once. My guess it that addPhoto: is wired up to some button click, dealloc would only be called once when the delegate is trying to destroy. This creates a situation like this:

• button click
  • alloc / init
• button click
  • alloc / init (memory leak on first alloc'd picker)
• close window
  • dealloc (free second alloc'd picker)

A better way might be the way Apple does it in the PhotoLocations and iPhoneCoreDataRecipes examples:

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
[self presentModalViewController:imagePicker animated:YES];
[imagePicker release];

Then listen for the didFinishPickingImage and imagePickerControllerDidCancel messages to your delegate and a call to [self dismissModalViewControllerAnimated:YES]; in both places should suffice.
