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.



Slyd is an easy-to-use, highly-customizable slider plugin for WordPress. There are plenty of plugins out there that allow you to easily insert a slider into your WordPress using a shortcode but they require creating a custom slide for every post you write.

With Slyd you can shirk those inconveniences. Slyd automatically pulls in all of your latest posts (or just the ones in a certain category). All Slyd requires is that you upload a Slyd image or a Featured image on your post page.

  • CSS3/jQuery Animations – Slyd is built to be pretty so naturally it uses CSS3 and jQuery to impress viewers.
  • Category Selection – Create a new Category or use an existing one to limit the posts that display in the Slydr.
  • Shortcode – Normal users can insert the [slyd] shortcode to display the Slydr.
  • PHP Template Tag – For more advanced users, install Slyd into a theme using <?php slyd(); ?>.
  • Responsive Design – Slyd is built to scale with it’s container, allowing it to look great whether it’s on a desktop, tablet, or mobile phone.

Plans for the Future

  • Themes
  • Custom Slyd caption for posts
  • Image Options – Fit (image stretches to fitwidth of container) or Center (image maintains original proportions ans can anchor to the center, any corner, or any side).
  • Animation Options – Slide, Slide Over, or Fade
  • Option to remove Slyd Image from a post


  1. Upload the slyd folder to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Either use the shortcode [slyd] in the page Slydr is to display or place <?php slyd(); ?> in your templates


How do I use Slyd?

Either use the shortcode [slyd] in the page Slydr is to display or place <?php slyd(); ?> in your templates.

How can I customize my Slyd shortcode?

The Slyd shortcode supports the following options:

  • category – Add the category(s) you want Slyd to be limited to. Default is all categories.
  • slydcount – How many posts you want Slyd to display. Default is 5.
  • nav – Determines how to display the navigation arrows. Options are show for always visible arrows, hide to get rid of the arrows entirely, or hover to only display the arrows when a user hovers over the Slydr. Defaults to hover.
  • height – Set the height for your Slydr. Must be defined in pixels, but don’t include the unit (i.e. height='500'). Defaults to the height of your tallest slyd image.
  • width – Set the width for your Slydr. Can be defined in any unit – i.e. %, px, em, etc. – and must include the unit (i.e. width='960px'). Defaults to 100%.
  • outline – Set an outline for your Slydr. Can be defined as any CSS readable color (i.e. #00f, #0000ff, rgba(0, 0, 255, 1), red) or set to none. Defaults to black.
  • show_titles – Show/Hide blog titles. Can be set to either true or false. Defaults to true.
  • show_captions – Same as show_titles, but for your blog’s excerpt.
  • caption_length – Set the length of Slyd captions in characters. Defaults to 150.
  • speed – Set the speed for your Slydr, i.e. how long a slyd will stay before switching to the next one. Define in milliseconds (1000 = 1 second). Defaults to 4000 or 4 seconds.
  • autoadvance – Set to false to stop autoadvance. Defaults to true.
  • use_featured – Determines when Slyd should use Featured images. Options are always to use Featured images instead of Slyd images, noslyd to only use it if there is no Slyd image, or never to only use Slyd images. Defaults to never.
  • no_links – Set this to ‘true’ to use Slyd as a slideshow. Defaults to ‘false’.
  • custom_loading_image – Set this to the path to your custom loading image, i.e. Disabled in this version
  • nav_images – Set this to the directory of your navigation images, i.e. This assumes your nav images are called next.png and previous.png respectively.
  • nav_prev – Set this to the path to your previous image, i.e.
  • nav_next – Set this to the path to your next image, i.e.

NOTE: custom_loading_image, nav_images, nav_prev, and nav_next all need an absolute path to your image. This means the path must include your domain name, i.e. /images/previous.png won’t work, but will. These four options will be heavily modified in the future to make them much simpler and more extensible.


[slyd category='foo' slydcount='3', nav='show' height='300' width='960px' outline='orange' show_titles='false' show_captions='false' caption_length='200' speed='3000' autoadvance='false' use_featured='false' no_links='always' custom_loading_image='' nav_images='mywebsite/nav_images/' nav_prev='mywebsite/nav_images/previous.png' nav_next='mywebsite/nav_images/next.png']
How can I customize my Slyd template tag?

The Slyd template tag supports the same options as the shortcode. Use all to get all categories, i.e. <?php slyd( 'all', 3,, 'always' ?>


<?php slyd( $category, $slydcount, $nav, $height, $width, $outline, $show_titles, $show_captions, $caption_length, $autoadvance, $speed, $use_featured, $no_links, $custom_loading_image, $nav_images, $nav_prev, $nav_next ); ?>

<?php slyd( 'foo', '3', 'show', '300', '960px', 'orange', false, false, 200, false, 3000, false, 'always', '', 'mywebsite/nav_images/', 'mywebsite/nav_images/previous.png', 'mywebsite/nav_images/next.png' ); ?>
