Newbie question on slideshows

[Stephan Hauduc]

I want a script that 'automatically' reads the number of files in a dir and
and then shows them in sequence.

Basically I have a program that outputs jpg's as slide1.jpg, slide2.jpg,
etc.and I would like a script that automatically finds how many slides there
are and plays a slideshow of them.

Ideally as well I'd like to be able to set different time lenghts that the
different slides are displayed for (maybe with these times in an external
text file, if this is possible then the number of slides in the dir will not
have to be auto detected but could be put into a parameter, and included at
the top of the timing file).

I have programmed many times before, but am a complete javascript noobie and
have no idea of how to do this - I'd really appreciate any help.

TIA

JavaScript can not retrieve a list of files available on the server in a
cross-browser, cross-platform manner. You could possibly use a Java Applet to
retrieve the list <url:

server-side technology to pass a list of files to client-side JavaScript.

There is one other alternative. If you web server provides a list of files in a
directory when there is no index.html present, you could load that into an
iframe and parse the results, although most web servers are configured to not
allow directory browsing.
