So, here's ANOTHER way to do the same thing..
1) install shozu (
http://www.shozu.com/portal/)
2) link to flickr
3) turn on geocoding and auto-upload new items in zhozu on the mogul
Now, to tag a spot - like your parking space - just snap a shot of it. It will get tagged and uploaded to flickr, where you can see it on a big map
Sorry, just another more complicated way to go
