[Theme: Zenon Lite] remove background from linked images in IE

My slides in the homepage Easyslider have a purple border (perhaps due to extra padding)in Internet Explorer. I realized after inserting a linked image in one of my internal pages that all images with links have a blue/purple border. Remove the link and the border goes away. How do I get rid of this? I do not have this problem in any other browser.

Here is an example of the linked images I have http://www.vskemanis.com/books/

Thank you for your help.
