Image pop-up question (not your pop-up plugin)

I want to have the ability for a paragraph to describe something, and then have a link that says “See an example”. If the user clicks the link, I’d like to display a graphic which has a close box to dismiss.

I looked at your very cool pop-over plugin, but that seems to display a single image coming in from, say, Google. It’s not apparently appropriate for content-specific pop-ups or pop-ups initiated from a link.

So, can you recommend something simple, say something that takes a URL to an image, and then when the link is clicked, shows the image?
