[OpenLayers-Users] GML layer choice for putting photos on a map,
clustering?

(Sorry if this is OT.)
I have a basic openlayers 2.8rc2 install on my server, with
OSM/{mapnik,tah} and OAM. I have a bunch of geotagged photographs, and
would like to render them on the map. My needs are pretty simple -
basically I want:
when there aren't too many photos, a small thumbnail
click on thumbnail pops up a bigger one, maybe with some text
when there are too many, some sort of clustering icon instead
I think I want to user the cluster strategy in the examples as
strategy-cluster*, and either georss from flickr example, GML, or KML.
But, it would be a slightly plus, but not much, if I published the
photos as WFS. I would also like to minimize work.
What GML language do people recommend? I have a slight bias towards a
truly open specification, so that makes me lean towards atom/georss.
Are there tools I should use, given a directory of images with exif gps
data, and perhaps caption files? I found
http://code.google.com/apis/kml/articles/geotagsimple.html
http://www.geowebguru.com/articles/108-technical-overview-georss
and it seems like a simple perl script to write georss from a directory.
Thanks,
Greg
