This is a Python script that matches photos on your computer with photos uploaded to Facebook. This helps you link from your blog or web site, to your Facebook photos. It is this script that lets me easily have photos on my blog that link to Facebook.
Using the Script
To use the script, you need Python, the Python Imaging Library, and JPEG Meta. A normal run of the script will take several minutes; if you're worried it has locked, you can use
python fbphoto.py [-v] [-d] [url] [path]
On all the photos that match an online photo, the script sets the JPEG comment block to the Facebook public URL for that photo.
Using Linked Photos
The main use for the URL is to automatically link to Facebook from your blog or web site. If you build your site using Pipp, URLs in JPEG comments are automatically detected, and a link constructed around the image. If you're using other software, you'll need to add your own hooks, or request the author add this feature.
Another potential use is exchanging more information with Facebook. For example, details who is tagged in the photo could be extracted, and added to the JPEG file. Alternatively, comments made in offline photo software could be posted as Facebook comments.
