Change Icons on Services Page

HI.

I’m new to Author, and I want to change the web icons at the top of the three columns on the Services page. The default icons are written in CSS. I have some in .png format I’d like to use instead.

Short of editing the CSS by hand, is there a way to replace the default web icons on that page?

I don’t have a lot of WP experience, I’ve always hand coded my sites til now, so forgive me if this has an obvious solution, but I haven’t found it yet.
