Downloaded the plugin but can't for the life of me figure out how to actually put a pop up on my site.
The notes here say for a single image you put
<a href="image.png"> <img src="image_s.png" alt="foo" /> </a>
But where to put it?! Adding it to the page simply adds an image to that page, not a pop up. Looked in the settings and haven't a clue.
