Solved: Dead link

On http://garmin.openstreetmap.nl/ Istanbul returns a dead link: http://undefined63240746.img/

Apparently this is the case for all links to individual tiles. It’s fixed now. Thanks for the report!

Istanbul link is still dead.

No it isn’t. Maybe you need to clear the browser cache or force a page refresh (ctrl-F5) first.

Thank you. I refreshed and could download the map.
