Difficulties in working out Product Showcase Slider module

[shopcarton]

Hi all,

just downloaded this free module from this site

http://dgcraft.free.fr/blog/index.php/free-prestashop-modules/prestacycle-slideshow/#comments

This module will actually give you a product slider showcase. Problem is you need to do alot of tweaking in terms of the size of the picture. After tweaking for some time, i am still unable to get it right. How can i frame the pictures within the slider, and also at the same time the picture does not get out of focus.

Currently my website url: http://www.shopcarton.com/prestashop/

I have attached snapshots of my CSS styling. Thanks in advance.
