I have a database of metadata that I need to write to about 3000 jpegs. I'm thinking of running exiftool via perl. Ie call up the database (MySQL) from PERL, loop through the filenames stored in the db , load each jpeg and write the metadata to the jpeg, save the jpeg and so on. More general question, can I add custom tags (name-value pairs) to the exif data in a jpeg? weather > rotten, that kind of thing. Thanks in advance. sparkie

Speedy reply or what! Thank you. I'll give it a whirl. The plan is to hoover up the tagged images into a DAM (Webnative Venture). I'll check with their support on the EXIF / XMP question. Mark
