[TYPO3-shop] showpic images

[amnava at eneconsultores.com]

I don't know like showing a small image in the single view and when click
over it,a window is opened with the same image but greater. How are
related both images?  When I click over the image, a window is opened with
the image with the same size.
 I want to do something like this

http://www.volarte.at/typo3temp/pics/1f01f7fd24.jpg this is the small picture
http://www.volarte.at/uploads/pics/lotic_1.jpg this is the big picture

Thanks,
Ana
