With J2STask, Abaca Press can automatically insert a banner containing their logo and some text extracted from the image IPTC metadata to ensure that the addressees know about the image rights. 

J2STask is a task manager designed to perform specific operations on graphic files such as filling in an IPTC field, rotating a picture based on the information provided by the camera (EXIF), downswing, re-compression, launch an AppleScript script, etc. 

Basically, a task scans a source folder and moves new files to a target folder after performing a specific treatment.
