SlideShare for WordPress by Yoast allows you to embed SlideShare presentations in your WordPress content types like posts and pages using the SlideShare WordPress.com embed code.
The plugin works with oEmbed so all you need to do is just paste the URL of the presentation in a new line. This is what we call oEmbedding, SlideShare for WordPress by Yoast extends it to slideshare presentations.
You can oEmbed presentatuions inside your posts, pages and custom post types and it will appear once the content is published. For more convenience, the plugin also includes an embed shortcode (just in case).
Start by installing and activating SlideShare for WordPress by Yoast
Once the plugin is activated, you can start oEmbedding your slideshare presentations.
You can set the max width for embedding presentations, visit your admin area dashboard Settings -> Slideshare page.
Earlier we have also discussed about a WordPress hack that extends oEmbedding to slideshare.
