 * 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.
