???

How can this script work on some pages but not others?

For example, try this page where the gallery doesn't work - it just pops the images in to a new tab or window
www.russellvilledental.com/implants/custom-abutments.html


Now, try this page where I used the same exact code, just a different directory, and it works (using Greybox - only one I can get to work)
www.russellvilledental.com/implants/biocad-implant-bars.html

Can anyone explain this?

Hi there!

With both the pages we have the same issue.
The strange is that in the HEAD part of the page I can't see the necessary sigpro code.

Can you please check out that your template loads the custom heads of the various plugins?
Thank you!
