I'm not sure what tech-forums thinks, but I'd stay away unless there is a really good, specific reason to do it. If you are sending your resume in for review for a position that is specifically asking for certification credentials or a certification from a manufacturer ... sure. But, in my opinion, graphics just make resumes looks too gaudy. If I were looking at a resume with a cisco logo on it, I would question the motives behind the person. It is hard to explain what I'm thinking, but think of your resume as your own advertisement. You are trying to sell YOU not some 3rd party company. There is no harm in certification pride, but that comes in thousands of ways other than showing off a logo from some firm that has nothing to do with WHO you are... after all... it's WHO you are not WHAT you are.
