Photo galleries for profile photos

Has anyone seen or can anyone envision a good way to sort many (50+) photos which are profile photos of staff members?

This is different from a traditional photo gallery because the emphasis isn't on the photo (i.e. we don't want it to zoom when clicked). Rather, choosing a photo lets you learn more about that person through there bio info that they've provided.

Furthermore, with 50+ photos, there should be an easy way to filter, (i.e. I only want to see people in finance, or finance and administration, or people who've been here for 3+ years).

Major kudos if this has already been implemented or can easily be forked from an existing app?
