I am very new to Jquery and have limited knowedge of it. I am trying to add this type of jquery pop-up form http://jsfiddle.net/hendriono/Jg8rd/show/ to my site www.whatiseewhenilookat.com, it uses Gallery3 site software to  http://galleryproject.org/.

I am having a nightmare trying to get this to work, I would be very grateful to anyone who can help me out with this
