Subject: [PATCH] image metadata editor
This patch adds an meta data editor for JPEG files. Currently title,
caption, artist, copyright and keywords can be saved. The data is saved
to the apropriate IPTC fields. Additional fields can be added in the
appropriate template.
Compatibility testing with other programs is needed!
