If you've done something quite unique and it comes up and you have pictures to show, I'd take them.
For eg: you organized a conference and there's a picture of you in front of 500 people opening the conference, take pics of that with you. It may come in handy.
Eg2: you climbed some interesting mountain, carry along some pics of you in the mountain top.
Eg3: you created an algorithm that sorted out a very difficult problem.
Don't take a flowchart of that along.Eg4: you mentored a young co-worker.
Don't take the coworker alongThe main theme is: take stuff that people would find very interesting regardless of a B-school interview. Don't display them right away, though, sense the feeling of the interviewer, ask whether they'd like to see some pictures and only then show them a few (2 - 3 max, not 25).
Hope it helps. L.
