PictureTagger provides a graphical front-end to the powerful metadata tag script, exiftool. Currently, PictureTagger allows a user to view a directory of JPEG images and to set or edit the IPTC tags for Headline, Caption-Abstract, and Keywords and the XMP tags for Headline, Description, and Subject. These tags are embedded within the image file itself. So, when the image is imported to a photo management application or uploaded to a photo sharing Web site, the application can utilize the metadata to automatically generate those properties for the photograph, including tags. This allows one to avoid being tied to any one application or photo sharing Web site by having one's hard work tied to an application specific data store.
Important NotePictureTagger requires mono, gtk-sharp, gdk-sharp, glib-sharp, galde-sharp, and exiftool to run. Of course, it will not compile without mono and the -sharp packages. You will not be able to load or manipulate pictures without exiftool. Fortunately, these should already be available as packages for your Linux distribution and easily installed through its package management program. Many Linux distributions already have the mono and -sharp packages installed for other applications that are installed by default, like f-spot, tomboy, or banshee.
