+ * @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.
