Pop Over Setup

I just installed Pop Up, I am not 100% on how this works. I installed it to my site and I placed some sample code from your site. Maybe I just don’t know the correct code to place in the pop over content? I got to the site and nothing shows up.

If there is a simple sample of code to place in? I just want to place a custom image in popover and have viewers click on it to go to a specific page.

If I can get a sample code to use or some kind of advice to make this work? The website is http://www.gasolinemag.com or email chad@gasolinemag.com
