* 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
