Adding Gallery to Dynamic Page

I know that there has already been a post about this, but I just cannot seem to get it straight.
Basically, I am setting up a website for an artist. She has a portfolio. This will be a gallery. When a viewer clicks on the gallery, I need it to go to its own page with several photos.
I have set up a database for the artwork with three rows of images. I can get the title and pagination working correctly, but with the gallery I cannot figure out how to get the code to display all three columns of images. I saw the post, but I just could not get the images to display correctly.
Thanks in advance!
