The generic use for info-slide:
[info_slide title="Title goes here" url="http://url.to/your/image.png" lazyload="false"]Your Content Goes Here.[/info_slide]
Lazy Load is default true if not included.
Additional options - height, width, margin, float
NOTE: The more attributes you add, the less responsive the result will be.
NOTE2: To use a shortcode like "[siteurl]" in the image URL, use "{" and "}" instead of "[" and "]".
I'll be adding a "shortcodes" page under "features" on future demos to list all the possibilities.
