+====== Website Thumbnails ======
+Sometimes you may want to create thumbnail previews of some webpages (eg. for a link list). Instead of doing this manually you can script it, too.
+The following script need the [[http://www.opera.com|Opera]] browser (you should be able to reproduce this with any other Linux Browser) and Xvfb.
+To install the latter on [[Debian]]:
+  #> apt-get install xvfb
+Create a file named ''urls.txt'' with one URL per line. Then run the script below like this:
+  $> xvfb-run -s '-screen 0 1024x768x24' ./webthumb.sh
+===== webthumb.sh =====
+<code bash>
+#!/bin/sh
+URLS=urls.txt
+IMAGES=images
+mkdir -p $IMAGES
+echo "starting opera..."
+opera -geometry 1024x768+0+0 -nosplash &
+sleep 20
+echo "done."
+for url in `cat $URLS`
+do
+  md5=`echo -n "$url"|md5sum|awk '{print $1}'`
+  img="$IMAGES/$md5.jpg";
+  if [ -e "$img" ]
+  then
+    #nothing
+    echo -n ''
+  else
+    echo "$url"
+    opera -remote "openURL($url)"
