I am continuously trying to geotag one photo in each of my travel galleries for places I have visited, etc. Once you click on the green SmugPin (above), you are taken to that image on the map. Clicking the image will then take you to the gallery where the image & other photos from that area reside.
Use the slider in the upper left corner to zoom
Click & drag the map to scroll
Click a map marker to see a thumbnail & caption
Click the thumbnail image to see a larger version
Click the thumbnails & then the links on the right column for tricky surprises
