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.

/*
Description:
	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.
