seanfitzroy said he would particularly like to add the date that the photo was taken. On my camera, you can set the date and time, and this is returned in the EXIF file as a field. Example:

DATE:15.11.2002 10:35

sean, your camera may not have this feature, but if it does, that might be a solution for you.

Thanks for the article, Derrick, I learnt a lot.
