Cardboard is a multimedia plugin for WordPress designed to enhance the viewing experience of 360-degree photos using Google Cardboard. This free plugin supports cameras like Google Street View and RICOH THETA, making it easy for users to integrate immersive content into their WordPress sites. With straightforward functionality, users can upload images directly from the WordPress admin screen, selecting 'Full Size' for optimal display, or they can utilize a manual shortcode for more control over the integration.

To use the Cardboard plugin, simply insert the image after uploading it in the Media section of WordPress. The shortcode format allows for flexibility in embedding the 360-degree photos, requiring only the attachment ID for setup. This plugin is an excellent choice for anyone looking to enrich their site with virtual reality capabilities, providing an engaging way to showcase panoramic images.
