Add a face to an endorsement

The common way to present people that endorse you is a bullet point list of names and titles. Make that much more powerful by changing that to a mosaic of faces. Avoid the uniform conference-speaker-headshot-gallery, rather:

• Use different image formats (B&W-color, suit-jeans, etc.)
• Use a different aspect ratio than the 3:2 passport picture (landscape for example)
• Use action shots (people presenting standing on stage)

Now this makes for a much more dynamic visualisation of the people who support you.
