Link does, indeed, have pictures: it takes only a moment for him to locate one of a strange, eerie underground space.

But Link has more to show, and after the picture he switches to an entirely different function - the map. The map is of a landscape that Ilphyl will never have seen before, but the stranger thing is that the map changes. Link presses a small icon at one side of the screen, and suddenly the map shifts from what is apparently the topographical landscape to what seems to be a bizarre alternate landscape.

If Ilphyl connects the dots, they might realises what this is - two maps of the same place, but with one above ground and one below.
