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.



After trying a plethora of gallery management plugins, I didn’t find one that I would want to provide for my clients. Up ’til now, I would use a plugin for home page sliders, a different plugin for a gallery widget, and a different one for galleries and slideshows embedded into posts.

Sliderly is my opinion of how galleries should be managed, whether they’re for a slideshow or gallery.

How easy is it? Click on the Slideshows tab, upload your images via the core WP Media Gallery, and Drag-and-Drop your images to re-order them. Show them on your site with a shortcode or a widget.

In the front end of things, I chose to go with Slides and Colorbox because they’re awesome, flexible, and reliable.

It comes with:

  • Quick edit access via a menu item.
  • Simple shortcode for slideshow or gallery.
  • [sliderly id=123 type=gallery]
  • Slideshows must declare their width and height [sliderly id=123 type=slideshow width=500 height=100].
  • To force links to open in colorbox (a pop-off-the-page image viewer), set colorbox to true [sliderly id=123 type=gallery colorbox=true].
  • Widget with intuitive interface for selecting gallery and type.
  • Hard-codable into a template via <?php echo do_shortcode('[sliderly id=88 type=slideshow]'); ?>.

For those developers out there,the javascript is found at js.php. With a little magic, you can leverage the backend of Sliderly with your own custom plugin.

In the back end of things, it creates a custom post type called slideshow and just stuffs a hash of info into the post’s content.


  • The drag-and-drop, ajax-ified management interface.


  1. Search for Sliderly in the ‘Plugin Gallery’ and use the one-click install OR Download sliderly and Upload the sliderly folder to the /wp-content/plugins/ directory in your own WordPress installation.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Use the shortcode [sliderly id=123 type=gallery] or use the fancy-schmancy widget.


What are the different `type` I can use for the shortcode?
  • gallery – displays a grid of the images in two columns.
  • slideshow – displays a simple, one-image-at-a-time slideshow with navigation controls.
  • featuredimg – displays the first image of a gallery, if colorbox=true, clicking on it will show a slideshow of the images.
What are the other features in the shortcode?
  • colorbox – links open in the glorious colorbox (inline dialog box), defaults to false
  • width and height – must be declared for the slideshow to display properly
  • controls – where the slideshow controls will be positioned (left, centre, right, hide), defaults to centre
  • grid – sets how many images wide the gallery should be, defaults to 3
  • effect – sets slideshow transition (slide, fade), defaults to fade
  • duration – sets milliseconds between slideshow slides, defaults to 2500

Add multiple files at once! – Thanks to Mike Jolley –
Fix where the Sliderly sidebar only showed 10 latest slideshows (limit is now 100).


Added donate button =) and unique ID for each slide. The ID is sliderly_{sliderly_id}_{slide_index}.


Added support for HTML slides, fade transition for slideshows, and slideshow slide duration. Also added “How do I use Sliderly?” in the admin panel.


Added support to hide slideshow controls with [sliderly controls=hide].


Added grid ([sliderly type=gallery grid=3]) for widget and shortcode. This lets you choose how many columns of images you want to see.


Added type of “Featured Image” for widget and shortcode ([sliderly type=featuredimg]). This will let you just add just the first image of a gallery to the page. If colorbox is turned on, it will show a slideshow of all the images in that particular gallery.


Sliderly plays better with other plugins now.


Support for moving the slideshow controls.


Make the widget extend to surround gallery. Backend drag and drop bug fix (being able to edit description, title, and link).


A few more if statements regarding output (declaring width and height only if present, caption and title only if present).


More silly changes regarding colorbox.


Properly require jQuery if not already required.


Fixed slideshow error if multiple instances are displayed on the same page.


Updated readme.


Gallery images stripped of their declared height and width.


Bugs fixed that shouldn’t have gotten by…


A first attempt at greatness.
