Python Bindings to Exiv2http://tilloy.net/dev/pyexiv2/
pyexiv2 is a python binding to exiv2, the C++ library for manipulation of EXIF and IPTC image metadata. It is a python module that allows your python scripts to read and write metadata (EXIF, IPTC, thumbnail) embedded in image files (JPEG, TIFF, ...).
It is designed as a high level interface to the functionalities offered by exiv2 (and is built on top of it). Using python's built-in data types and standard modules, it provides easy manipulation of image metadata.
