Thanks for replying. I promoted your suggestion on the link you sent. 50 million geolocated photos is vey impressive and I agree would be an incredible resource for ArcGIS.
Do you, or does anyone else reading, think that including the panaramio feed in an ESRI web mapping application would be possible with custom programming? The organization for which I work would be willing to hire someone to build this kind of functionality for us if it is.
