How do I remove the border around the images in my header?

I am trying out a new theme, and I want to keep the old header, which is a few pics with links. The theme has a thick blue border around all of the images. How do I remove the borders? http://PWNEDvideo.com . Thanks!

 

It's either in the CSS file, and you'll have to hunt down the global settings for all images and remove the border, or its an image frame that displays behind the images.
I would check that first...check the theme's image folder and see if anything looks like it could be the frame. If so, delete it from your installation...if not, then it is probably a CSS setting.

 

put code below in your CSS file.

a img {
border: none;
}
