A simple go program to parse .picasa.ini files and create HTML pages with thumbnail for each face and links to original image.
Requires ImageMagick 7+ for the thumbnail creation.
go build
./picasa-faces -base /path/to/images/
This will recursively visit all subdirectories under the base path, looking for .picasa.ini files. The results will be in /Picasa-Faces:
/path/to/images/Picasa-Faces
index.html
Jane+Doe.html
Joe+Schmoe.html
...
thumbs
thumb00000.jpg
thumb00001.jpg
...
The index contain links to each person's thumbnail page; each of those contains thumbnails cropped to the Picasa identified face.
