/* Version 1.0:
 * Once I first found out that it was possible to have pixel level control
 * of HTML tables I instantly realized that it would be possible, however
 * pointless, to save an image as a, albeit huge, HTML table.
 *
 * One night when I was feeling in an adventourously stupid programming mood
 * I decided to write a program to do it.
 *
 * At first I just wrote a really ugly hack to do it, which I then planned
 * on using once just to see how it worked, and then posting a URL and 
 * laughing about it on #gimp.  As it turns out, tigert thought it actually
 * had potential to be a useful plugin, so I started adding features and
 * and making a nice UI.
 *
 * It's still not very usefull, but I did manage to significantly improve my
 * C programming skills in the process, so it was worth it.
 *
 * If you happen to find it usefull I would appreciate any email about it.
