It doesn't have to be a screen door, and as far as I understand, it's not intended to be with iOS 7. The phone will not let you sync with an unrecognized external device unless you unlock it, and will stop you from brute forcing the passphrase, as well. Unless you physically take apart the device to remove the flash storage, I don't think there's a way to access the photos on it.
