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
