The project has now been taken over by ZenPhoto at http://www.zenphoto.org/trac/wiki/ExifixerLibrary


Exifixer

I wrote this PHP library to do a better job at reading the EXIF data embeded in images taken from digital cameras. If you have PHP compiled in a certain way, you may already be enjoying some functions that do this to some degree, but the default implementation fails to parse all the embebed tags. My library will read many, many more tags, and it will work without needing to compile PHP with the exif option.

This script has been tested with the following digital cameras:

Nikon CoolPix 700, Nikon CoolPix 4500, Nikon CoolPix 950, Canon PowerShot S200, Canon PowerShot S110, Olympus C2040Z, Olympus C960, Canon Ixus, FujiFilm DX 10, FujiFilm MX-1200, FujiFilm FinePix2400, FujiFilm FinePix2600, FujiFilm FinePix S602, FujiFilm FinePix40i, Sony D700, Sony Cybershot, Kodak DC210, Kodak DC240, Ricoh RDC-5300, Sanyo VPC-G250, Sanyo VPC-SX550
