Yes, you're right - there appears to be a bug in
Image::Info.  EXIF has a Comment field.  There is also
another non-EXIF field named JPEG-Comment which is
part of the JPEG/JFIF specification.  Image::Info
apparently has a bug that prevents it from accessing
either of these fields.  In IDS 0.82, you make
reference to the Comment field on line 696 of
/ids/index.cgi and attempt to merge it with  the
contents of the text comments saved by IDS.  However,
since Image::Info always returns null for Comment, the
IDS code on line 696 doesn't do anything.

There is other useful JPEG info such as Title,
Keywords, Caption, Categories stored in the IPTC
metadata.  See
http://multipart-mixed.com/photo/iptc.html for a perl
script that extracts IPTC data.
