I am fairly sure this would be a java script but I am looking to have a set up on a standard single page website where images can be clicked on and
enlarged and then clicked again and brought back down to standard size. I do not want a redirect to a different page or have to have them save it.
You might like this other one called Lightbox too. I've used it before in the past. It's more of a showy image display technique so I wasn't sure
if it was too much for what you described.
