I recently got an email from Schmap Guides asking if they could include one of my photos from Nice that I posted on Flickr. Cool! I checked out the site and it looked very nice. I retain rights to my photo so it was a respectful usage of my photo. I agreed and it was included.
I did some investigation of the web site and application. It is a map based city guide that takes content from W Guide and photos from Flickr and puts them all together on a map. It actually looks pretty useful for travelers especially the new option for downloading the guide to an iPhone or iPodTouch.
You can view the guide on-line or download a PC or MAC application to view it on your PC and make modifications. It also looks like you can customize and create your own. You can also get widgets.
Anyway - here is link to my photo on Schmap and the widget below which circle through the museums and includes my photo.
