First of all, I'm not good with JavaScript at all. I followed all instructions on this page: http://www.lokeshdhakar.com/projects/lightbox2/
Visually everything loads fine. However, visual studio throws this error while running. If I hit continue everything seems to be loading fine. I see all buttons, animation, etc. I can only guess that something not loading properly. But not sure..
I think i had the same problem as this. In the end I decided to go with this version of a different lightbox instead as it works like a jQuery plugin

For me I felt it was a lot nicer since it worked with jQuery as a Plugin, and didnt rely on the 6 js files!
