When I download an image the app immediately says "Image downloaded" while the image is seems to actually dowloaded a bit later or, what's worse, not at all.
When you save an image, it is copied from the cache because it was already loaded for display. It's a fully local operation. Or do you mean it appears in photo gallery apps with a delay?
