IPTC (see: http://www.iptc.org/pages/index.php) is a format (?) of 
including text-info into an JPG-graphic. Most of the newer graphic-viewers 
(like XnView and irfanview) and - editors support it.
you have different fields (like author, date, titel, caption, keywords etc) 
to store within the image-file.

There is  a native PHP(4) funtion described in 
http://us4.php.net/manual/en/function.iptcparse.php

There is an implementation for another PHP-Gallery here: 
http://tim.digicol.de/gallery_iptc/:
 >> For advanced users: Note that PHP has full (while currently poorly 
documented) read/write JPEG IPTC support with the 
<http://www.php.net/manual/en/function.iptcparse.php>iptcparse() and 
<http://www.php.net/manual/en/function.iptcembed.php>iptcembed() functions. 
<< (I will check this)

Also there is a PEAR-class (see: 
http://pear.php.net/package/Image_IPTC/docs/1.0.2/Image_IPTC/_Image_IPTC-1.0.2_IPTC_php.html) 
which can be used to extract the info into an array:

suggestion: the extracted IPTC-data could be put into std PmWiki 
Format-variables which could be included in your WikiGalleryOutputTemplates 
- if desired - for viewing images and Text.

I can also see the next days how to include this and give you some code 
snippets when I installed your module for testing.

btw: another interesting feature is EXIF - like IPTC but included 
automatically by a digital camera into it pics
