Inserting a Gallery using a shortcode.
[gallery modal=”true” post_id=”1234″ title=”My Slideshow” thumbnail=”/wp-content/my-theme/images/my-thumbnail.png” thumb_class=”gallery-thumb”]
Setting the modal parameter to false will add the gallery directly on the page, setting it to true will allow you to create a clickable thumbnail with a gallery that opens in a modal box. Setting the post_id parameter will pull the gallery from a specific post, leaving it blank will use the id of the current post. Title can be used to set a title. Thumbnail is used to set the source of the thunmbnail image. The thumb_class parameter can be used to add a class to your thumbnail image.
Added images using the normal WordPress image media uploader.
