Using http://openlayers.org/dev/examples/xml/georss-flickr.xml as a GeoRSS feed containing photos.
Adapted from the example at http://openlayers.org/dev/examples/georss-flickr.html.

A map with user locations can be made by using the enabling user location and overlaying a map with a georss user feed.

Steps to reproduce:

• go to /?q=admin/user/settings and enable the location fields for a user in the Mapping kit section.
• the account edit pages now show a location category page; enter lat/lon coordinates for some accounts and check that (the source of) ?q=user/feed contains <georss:point> items
• go to /?q=admin/user/permissions and give the 'access user profiles' permission to anonymous users.

A GeoRSS layer can be added to a map with e.g. [map context="node/25/context" layers="1" 1="georss|/drupal-6.x/?q=taxonomy/term/2/0/feed|Layer_Title|options"/].
The Layer_Title is optional; if it is missing, the layer title will be taken from the RSS feed. The Icon_URL is also optional; if it is missing, the default OpenLayers marker will be used.
