Please, here is my little code for creating thumbnails of pictures saved in a folder named 'pictures', and saving them in another folder named 'thumbs'.
! /bin/bash

do
convert -thumbnail 100 pictures/$i thumbs/$i
done
However, there two things the program doesn't do:
1) It does not retain the name of the pictures in the thumbnail.
I have the following code which is supposed to convert the first page of PDF to thumbnail:
<?php

?>
My host server is Siteground, and apparently /usr/bin/convert is where ImageMagick convert function is.

Openoffice odt files display a thumbnail (of the first page) in Nautilus file browser. Same with pdf files. These thumbnails are created by Nautilus using tools such as gsf-office-thumbnailer and evince-thumbnailer.
I am working on creating system monitoring graphs from sar outputs. Ksar seems to be a nice gui tool, with some command line support. My goal is to create pdf/png charts from a script using ksar command line.
The released version has some minor bugs where I got some exceptions. Fortunately the beta 5.1.0_beta4 does not have the bugs and produces nice graphs from GUI.
