Display Media Gallery Without Thumbnails

Does anyone know how to place a gallery on a page that is linked to the main menu, so that when users select that link, instead of seeing thumbnails, the gallery automatically opens and allows the user to go forward and backward through the images in that gallery?

I do not want users to see thumbnails, and I cannot find a shortcode that suppresses thumbnails anywhere on or off the WordPress site.

Visit http://www.trnimen.com and look at the branding or design links to see what I mean. Thank you for your help!
