This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



The plugin takes an image source (e.g. RSS feed or web page), passes
it through XSLT via the
plugin, then uses javascript and css in the client to do the actual

Because of the use of XSLT, it’s fairly flexible, allowing new image
sources to be made available quickly.

It’s still under development, but working nicely on Firefox 1.5, 2.0,
IE 6 (Win) and 7. Please feel free to submit bugs and suggest features
by posting questions etc on the
home page.


  • Javascript.
  • DGE_InlineRSS
    plugin version 0.93 or greater.
  • Only tested with WordPress 2.0 and 2.1. I don’t know if it’ll work
    with earlier versions.
  • PHP 5.


The latest stable version with various applications of the slideshow
is here.

The latest trunk is up and (probably) running


You can invoke a slideshow by either placing a specially formatted
string into any page or post, or from your theme templates with a call
to DGE_SlideShow function. For both methods, the arguments are the
same, but the call is different.

Both methods of invokation require:
* a unique id
* a url to fetch
* options

The id must be unique for each slideshow, and must be a valid
javascript variable name, with the exception that it may start with a
number. So it must not contain spaces or dashes, for example.

Filter method

When you activate the plugin, it installs a content filter into
wordpress. This filter looks for strings beginning with !slideshow!,
followed by the 2 required parameters, and a list of options. Each of
these parts of the filtered string must be separated by an exclamation
mark. Options must be separated by a semi-colon. If you want to
include more than one slideshow in succession, make sure they are
defined on a new line for each call.

Here’s the syntax:


Here’s a few examples:


From php (your theme templates)

The DGE_SlideShow function takes three parameters. The first is the
unique id for your slideshow, followed by the url of the desired feed,
followed by an array of optional arguments. The function returns a
string with the necessary javascript and html to set up the slideshow,
so just echo it.

For example:

// From version 0.3 and above
echo DGE_SlideShow('ss1', '', array('limit'=>5,'reverse'=>1));<h3>Options</h3>


  • Limits the number of images extracted from the feed. Default is 0,
    implying no limit, or everything in the feed.


  • Applies the options defined in the named preset, before overriding
    them with any other options passed.


  • This option doesn’t need any value. Just by being present, it tells
    the plugin to reverse the order of the images in the feed.


  • Specify the time in minutes before the cached html is refreshed. Set
    the default in the options pane. It is 1 hour by default.


  • Specify a particular xsl translation file


  • Assume input url is HTML, rather than XML. (As of v0.392)


On the slideshow options page, you can set up presets to save you
typing the same options in for different slideshow calls. Just give
the preset a name in the left-hand field, and fill in the right-hand
field with the desired options in the same format as the filter
call. That is, separate each option with a semi-colon.

For example, the name of your preset might be preset1, and you want
to always reverse the feed, and have a timeout of only 1 minute. Fill
in the left-hand field with preset1, and the right hand field with

Another example would be to add a shortcut for Zooomr favourites. Put
zooomrfaves as the name, and xslt=dge-slideshow/xsl/zooomrfaves.xsl
in the value field, again omitting the quotes. You could then invoke a
slideshow of a Zooomr set with:
