  • Download and place the file(s) in a directory called JavascriptSlideshow in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    require_once "$IP/extensions/JavascriptSlideshow/JavascriptSlideshow.php";
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Options / attributes[edit]

The id to be given to the div containing the content. This allows you to pre-specify the id for styling purposes. If none is specified, the id will be a randomly generated number starting with 'slideshow_' (e.g. slideshow_12345).
The time, in milliseconds, between transitions. The default is 1000 milliseconds (one second).
The sequence in which to display the content. Must be one of the following values:
  • random: This is the default.
  • forward
  • backward

How to transition (change) between content. Must be one of the following values:
  • cut: A straight cut from the current content to the new content. This is the default.
  • fade: A one-second fade between the current content and the new content.
  • blindDown: The new content "rolls down" over the existing content.
The time, in milliseconds, that transitions take to complete. The default is 400 milliseconds. Increase it to make transitions slower.
if 'true', center the slideshow (only works for a slideshow of images, not text).



<slideshow sequence="random" transition="fade" refresh="10000">
<div>[[Image:Image1.jpg|thumb|right|128px|Caption 1]]</div>
<div>[[Image:Image2.jpg|thumb|right|128px|Caption 2]]</div>
<div>[[Image:Image3.jpg|thumb|right|128px|Caption 3]]</div>

This results in a div (with a randomly generated id) that randomly changed every 10 seconds between the three images specified (which happen to be wiki images).

Parser function[edit]

|id=bar refresh=1000

would result in a div (with an id of bar) that changed every second between the words Tick and Tock.
