Originally designed to allow press photographers
to provide information concerning images they sent back to the home office,
IPTC fields can be used to store supplemental information about an image.
IPTC information differs from EXIF information in that EXIF information
is generated by the digital camera and contains information about various
IPTC fields can be used to “annotate” images with a great
deal of information.
BPP has the capacity to read and display IPTC information. BPP can display
IPTC information anywhere it can display EXIF information. For example,
BPP can display comments contained in the IPTC Caption field and will
display them below the slide image. In order for this to occur, the “IPTC
Caption” option must be checked in the “Comment sources” section
of the JAlbum Settings-Advanced-Metadata
tab. BPP can also display IPTC fields as Thumbnail
Captions, and Slide
BPP can also display IPTC information in the EXIF information window.
To do this, Meta
Data Custom Fields must
be edited to contain the IPTC tag names desired (more information on
how to customize this uservariable is available at the Customizing
the metadata information displayed section.
The following IPTC tag names are available (grouped by the tabs found
(the Urgency field seems to use special codes;
for example, setting the Urgency to ‘High’ results in the
field value of ‘49’)

The screenshots to the right show the various IPTC fields as viewed
from a wonderful piece of freeware software, Irfanview (another freeware
product, Exifer, can also edit IPTC and EXIF data). Because the IPTC
fields are “freeform”,
they can accept any text. It is not necessary to fill in IPTC fields
field names (although if displayed in the EXIF information window, the
field name will appear and may be misleading to the album viewer).
There is a wonderful
tutorial written by Gordon Dodge available on the
JAlbum forums; Gordon explains in detail how one might use IPTC fields
together with BluPlusPlus.
