Adding a lightbox function to scrolling thumbs

Ok now this is pretty basic but I’m still getting my head roung jquery.

I have a basic scroller which I want to add a lightbox function to each of the thumbs contained in the scroller. I have tried but it just messes my scrolling of the thumbs function up.

this is the method I used for my scroller

and this is my html - I have removed the references to the jquery for the lightbox etc and was hoping someone could point me in the right direction.

(quick note before I forget: You should get in the habit of adding your javascript files near the bottom of the page, not in the head…it’ll make your site appear to load faster).

Other than that:

I recreated the demo in this page:
I entered in your structure here, but kept the same javascript:

You need to put divs around your image groups for one. And as for the size: 4, it doesn’t seem to recognize it, even in the demo…so I’m guessing that’s an invalid parameter.

What would you suggest the best method would be to get the smaller images in the slider to open a larger preview in a lightbox?
