Go back to standard image popup from Cloud Zoom

Hi,

Recently got me a template where the image popup uses Cloud Zoom instead of the standard one. But it does not fit my page, and I would like to go "back" to the original one, where you click the image, and get it in full size.
Can anyone tell me how to make this change?

Btw. I can not use vQmod as it do not work right on my setup.

Regards

Why don't you ask theme author for supporting?

They don't really respond on my emails.

All I want to do is uninstall/remove Cloud Zoom from Colorbox.
