 * @author Patrick Cool, patrick.cool@UGent.be, Ghent University, May 2004, http://icto.UGent.be
 * Please bear in mind that this is only an beta release.
 * I wrote this quite quick and didn't think too much about it in advance.
 * It is not perfect at all but it is workable and usefull (I think)
 * Do not consider this as a powerpoint replacement, although it has
 * the same starting point.
 * This is a plugin for the documents tool. It looks for .jpg, .jpeg, .gif, .png
 * files (since these are the files that can be viewed in a browser) and creates
 * a slideshow with it by allowing to go to the next/previous image.
 * You can also have a quick overview (thumbnail view) of all the images in
 * that particular folder.
 * Maybe it is important to notice that each slideshow is folder based. Only
 * the images of the chosen folder are shown.
 * On this page the options of the slideshow can be set: maintain the original file
 * or resize the file to a given width.
