BlitzIQ for images sets a new standard for finding your images in that ever exploding gallery.
Finally you can find an image based on where you remember it being taken.
Where you remember it being taken - is different from knowing where you took it.
Find my pictures around the Space Needle rather than - well how you used to scroll through the gallery for that elusive picture while the conversation moved on.
