Up.gif and down.gif not displaying in cart

[Intellivapor]

Hello,

We have just started using the AbleCommerce (7.0.4) and everything seems fine, except when we add an item, then view it in the cart there are placeholders for <More> and <Less> however the images are not being displayed - if you go to the homepage, click on add to cart and you will see what I mean.... http://www.intellivapor.com

I have checked and it does appear to have a folder labeled "images" off the root directory and the images up.gif and down.gif are there.

Any ideas????

Thank you for any help you can give!

James
