photolog update

This weekend I made some changes to my photolog. On the backend there's now a database keeping some meta-info about each picture. (Previously, it was using the filesystem only.) On the frontend, some of the photos now have a [details] link after the title that leads to a page with the meta info for that particular photo. For example: I'm adding some of the metadata like title and keywords by hand. But some of it is automatically included by parsing the exif data embedded within the image. Exif data includes technical details about the shot: exposure time, focal length, aperture setting, etc. To get the exif info I'm using a program called exiftags. (jhead is another good exif data extractor that I found while putting this together.) I'm hoping that having this technical data about the shot a click away from each photo will help me remember what works and what doesn't.
