I'm using Shadowbox.js to display an interstitial ad on our website through DFP, as a Third-Party Code creative. It works great, you can see it here: http://sandiegomagazine.com/.
I would like to either have shadowbox close after 10 seconds, or display once per browser session. Can you help? I would be much obliged.
Thank you for your response and time.
My code is below, and is being funneled through a 1x1 ad placement through DoubleClick for Publishers.
