FlickrBrowse uses a custom WFS Feature:
The class is here:
Note that from processXMLNode, an 'icon' is returned:
icon: new OpenLayers.Icon("http://farm"+attrs.farm+".static.flickr.com/"+attrs.server+"/"+attrs.id+"_"+attrs.secret+"_s.jpg", new OpenLayers.Size(Math.max(25, (75-this.layer.markers.length*3)),Math.max(25, 75-this.layer.markers.length*3))), popupContentHTML: html, popupSize: new OpenLayers.Size(275, 220), id: null};
This Icon is used by the WFS class to display.
![http://farm"+attrs.farm+".static.flickr.com/"+attrs.server+"/"+attrs.id+"_"+attrs.secret+"_s.jpg](http://farm"+attrs.farm+".static.flickr.com/"+attrs.server+"/"+attrs.id+"_"+attrs.secret+"_s.jpg){kind=link}
