Hi,

fyi: imagegallery is part of kipi-plugins.  kipi-plugins are discussed on
kde-imaging mailing list.

htmlgallery plugin, a replacement for Imagegallery is under development. You'll
find it in KDE svn trunk/extragear/libs/kipi-plugins/.  At addresses the adoption of
look.  Not sure about exif infos (I havn't tried the new plugin yet).

You need to link against libkexif too.  You should have already the
-devel pkgs installed otherwise it would have complained earlier
about missing header files.

  To me vi is Zen.  To use vi is to practice zen. Every command is
  a koan. Profound to the user, unintelligible to the uninitiated.
  You discover truth everytime you use it.
