How to remove blue line under product images?

[Blackbeltpatches]

There is a blue line under the product images in the site I am setting up (inbetween the image and the words 'larger image'):

These blue lines only appeared after I removed a failed installation of Zen Lightbox.

How can I get rid of them?

Thanks in advance for your help :)

It worked, brilliant!
