Create MediaRSS feed with PHP from info in MySQL-DB

The project involves creating a MediaRSS feed (basically an RSS feed with some extra fields) from the information in a MySQL DB. In the DB jpeg images are in a table (by filename) and in the same table there is a field (yes/no) that is used to determine if the image should be in the MediaRSS feed or not. The MediaRSS feed will be used with CoolIris I will send you the DB before the start of the project.
