As long as you know the filename, performance will not be an issue. However, if you don't know the full path, then you may want to either redesign the app or consider storing everything in the DB. The apps that I've seen had the full path stored in the database, and the image on a file server. I've also had apps that stored everything in the database, and that turned out to be a nightmare. Eventually, we moved everything from the DB to the filesystem. Corey
