The PHP EXIF Library can both read and write all EXIF tags.Reading the EXIF tags and embedded EXIF thumbnail from images taken by a digital camera gives you a wealth of information about your image. This includes the exact date and time the image was taken (which is generally different from the time the file was uploaded to your server) and detailed information about the camera settings such as the F-number, the shutter speed etc.By making it easy to write EXIF headers to images, PEL makes it possible to annotate images with comments. These comments can of course be extracted again using PEL --- storing the comments directly in the images means that the comments are where they are needed: with the images.The main features of PEL are: reads and parses JPEG and TIFF images, supports internationalisation (English, Danish, German, Spanish, and French), extensible object-oriented design, unit-tested with SimpleTest, documented with PhpDocumentor.
