Very, very cool.

However, could you please make a "Captivate for dummies" page. I guess
that I could figure it out with some investigation, but I am not sure
when and how you generate the thumbnails, on what you run captivate,
etc.

I saw:

  You should put some default values in /home/hugo/.captivate.rdf.
  Sample: http://impressive.net/people/gerald/misc/dotfiles/captivate.rdf

You should pause for a few seconds here, because I would never have
seen those messages if I hadn't piped the whole output into a file.
:-)

Also, I got a bunch of "Use of uninitialized values" but I can't
reproduce that apparently.

Here is what I currently do:

  1. Put my pictures in a directory, named HH_MM_SS.jpg.
  2. Make thumbnails, generating HH_MM_SS-sm.jpg, by running:
     make_thumbnails *.jpg
  3. Generate an index page: make_image_index *sm.jpg > my_index.html
  4. Edit this page: vi my_index.html

make_thumbnails is the script you wrote on 11 January 1999.
make_image_index is a slightly improved and customized version of your
original version of 11 January 1999. I am attaching them both for
archival purposes.

How do you put a set of pictures online? If you rotate a picture, are
you not losing the EXIF information? If so, can your script handle
this?

Finally, a remark: RDF documents on impressive.net are served as
text/plain.
