Yes, that popping out to Google.maps is a bit of a pain.
"I'll have to think about it"
Les (Fahrside) has been a great help. In fact, it was mostly because of him that this is getting done.
Showed me patiently how to do it, and made about half of the new maps himself.
We do have most of (but not all) the maps ready, but I wanted feedback on "Beta" page before hand. So when I edit the pages to include the new maps I don't have to redo them all again and again
