Johannes Ullrich provides some handy scripts for mining data from the popular picture hosting site TwitPic.

Over two-thirds of the images contained detailed EXIF information, providing wealth of info about the device used, location, even cardinal orientation and direction of travel from your handy iPhone.  A small number of files also revealed the photographer’s name.  Summary findings and a link to the scripts are available on his blog.

Hardware manufacturers for a subset of the TwitPic dataset.
