Re-adding team + pet photos to source/images/press

Why is this change being made?

Not sure what happened since it was added last week, but the logo mosaic with team member photos and pet photos has disappeared and as a result is no longer available on the website under Press Kit. @dmurph can you please merge when you get a chance? TIA!
