/**
* 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.
*
* Each slideshow is folder based. Only
* the images of the chosen folder are shown.
*
* This file has two large sections.
* 1. code that belongs in document.php, but to avoid clutter I put the code here
* (not present) 2. the function resize_image that handles the image resizing

*
* This code should indeed go in documents.php but since document.php is already a really ugly file with
* too much things in one file , I decided to put the code for document.php here and to include this
* file into document.php
