This is an example displaying a standard WordPress gallery set at the top of a post. This text will stop displaying on the blog index page wherever I decide to place a read more tag.
The read more tag is an option within the WordPress post/page editor and is button labelled ‘more’ – simply click to insert within your content where you wish. You may of noticed that this post is also displayed within a full width template rather than a sidebar. This is easily done by simply choosing a template when creating a new page or post.
