Product Page Style

I would like to get my product page looking like it does after I click the image…. Before I switched the theme in General setting the product would open in lightbox… Now That I switched to Custom , I like the way it looks after you click the image once…

No sure how to make it display this way from the get go…

Take a look at screencast and let me know please how to fix
