The XMPjpegGenerator extracts \[XMP\] from a jpeg file. This AdobeTM XML can encode metadatas like title, author, description... This schema implements an open standard known as \[IPTC/IMM\]. For your photos, try for example an app like \[pixVue\], it allows you to add different infos, encoded in jpeg headers, with also an XML/XMP embed. If you don't like to deal directly with the ugly  Adobe XML, see here http://wiki.apache.org/cocoon/XfolioXmp2dc.xsl

\[XMP\] Adobe Systems Incorporated "Extensible Metadata Platform (XMP)"  http://www.adobe.com/products/xmp/main.html  Adobe's Extensible Metadata Platform (XMP) is a labeling technology that allows you to embed data about a file, known as metadata, into the file itself. With XMP, desktop applications and back-end publishing systems gain a common method for capturing, sharing, and leveraging this valuable metadata -
opening the door for more efficient job processing, workflow automation, and rights management, among many other possibilities. With XMP, Adobe has taken the "heavy lifting" out of metadata integration, offering content creators an easy way to embed meaningful information about their projects and providing industry partners with standards-based building blocks to develop optimized workflow solutions.
