Change Detail Page to Pop-up Picture

[gthomas2]

Can anyone tell me how I can change this..........

 

When the 18 products are listed on a page and when you "click" on the picture you are redirected to the products' "Detail Page" and what I would like to do is have it show the enlarged pop-up picture in a new window instead.

 

If this is possible, could someone direct me to the source?

 

Thanks in advance,
