Loading lightbox gallery from only one thumbnail pic

Hi, I am newbie on WP and i am stuck on very simple gallery based problemo.
my intention is having one page/post with one image and some text body.
This single image on post/page, when clicked by surfer, pops out lightbox gallery so that user can browse through all images.
In this way my post/page is not crowded by all the images contained in galley. But seems like most of the solution offered by plugins is dumping all images on post/page.
Please help,
thank you.
