Bug ‘resurrects’ deleted image thumbnails in iOS 7 Photos app

Despite being discovered in iOS 5 last year, a possible caching bug in Apple’s iOS 7 Photos app still allows thumbnails of deleted pictures to be “resurrected” by saving a transparent PNG file to the album.

The thumbnail restoration issue as applicable to the latest iOS 7.0.4 was spotted by AppleInsider reader Mike, while a quick check confirms that the small previews associated with deleted pictures do indeed reappear when a transparent image is saved to the Camera Roll. Full size pictures are not restored.
