Yeah, here is one. Have a look at my page: http://foto.schonhose.nl
. If you open up the sidebar there is a link for the gmap view (last item on the info window)and it also uses the lightbox principle.
Also have a look at the map
which uses clustering and a nice flickr like plugin to show the thumbnails of the clusters.
Did I mention it can read GPS values from the EXIF and you can tag when you upload an image by placing a marker on googlemaps? No need for a specific PHP version though. I have been working on it for the last four months or so, completely rewriting the old Googlemaps addon.
