Update. It does work in IOS but you have to click near the top of the image in the centre to get the overlay with links to appear, when it does appear it then goes either straight to the larger image link or straight to the link. Which one it goes to depends whether you tap slightly left or slightly right of the top centre of the image. Slightly left takes you to the larger map, slightly right takes you to the link. Easy if you know that but most people will give up before discovering this. Not intuitive. Also sometimes the overlay appears but the links just don't work.
