Images are a great way to liven up an “about” page on a web site or a team page in a presentation. The best images are the one where all team members are present in one image. You can overlay name tags and get a great composition. No issues with images in a different style, images that are outdated. And it shows how well the team works together.
Second best alternative is individual images. But please avoid selfies. Most people assume that where-is-the-button-I-need-to-press look when taking a selfie. It does not come across very professional. The least you can do is ask a colleague to take a quick picture with your phone if you are in a hurry.
