Since Flickr added the geotagging feature, more than six million photos have been tagged on the map. However, if you want to know which places have the most photos tagged, that information is not available on the Flickr Map. Fortunately, we have Google Earth. To understand the distribution of photos on the map, you can simply download this KMZ file, "Flickr Photo by Location," from this site. Once downloaded, you can view it in Google Earth, where you'll see squares ranging in color from red to yellow, representing the number of photos in each area, along with precise photo counts displayed above each square.
