When creating my online photo galleries, I wanted to be able to display the EXIF fields that were contained within the JPEG picture files. I was using Perl for the script, but I couldn't find any Perl code to read the EXIF data. I had to write it myself.
The following is a link to the script I use on my web site. It's not too pretty, and it contains some code that's only applicable to the EXIF data written by Casio digital camera, but it does the job.
I don't have any plans to add support for other cameras (a bit difficult to do since I don't have any other digital cameras), but feel free to add your own support.
