/*
        With the following code, Slimbox will activate itself automatically on all links pointing to images,
        or more specifically all links having URLs ending with: ".jpg" or ".png" or ".gif".
        As a result, you will not need to set the rel="lightbox" attribute on any link to activate Slimbox.
        Furthermore, all image links contained in the same block or paragraph (having the same parent element)
        will automatically be grouped together in a gallery, so you will not need to specify groups either.
        Images that are alone in their block or paragraph will be displayed individually.

        Replace the default autoload code block with this one.
