Photostack/Photo Gallery Centering on Screen


AndrewFerrara

Recommended Posts

Need to have the javascript photo gallery on this page http://www.halogamertags.com/dachs/ center on the screen.

 

For example if you scroll down to where the second puppy is at the top of your browser and click on the thumbnail the gallery is at the top of the web page.

 

Thanks,

Andrew
