Hey everyone - first time poster, yippee!

Anyway, I'm having trouble getting my lightbox to work correctly. I'm working on the page at www.seabirdcreative.com/portfolio.html

I followed a video tutorial on YouTube showing how to code this, get it all installed, etc.

Hopefully someone can tell quickly by looking at it what I'm doing wrong. The thumbnails are all there, but they don't do anything when I click them. If I right click them and open in a new tab, they open, but this isn't the Lightbox I was looking for.

Help! Thanks!
