Display featured members

Hi,

Can someone help me to display featured members? Much like the featured listings…
For example lets say everyone on membership package ID 4.. I want their accounts the be featured. Basically the users photo.

Would be something like:
$getMembership = get_user_meta($userdata->ID, ‘pptmembership_level’, true);

if ($getMembership = 4) {
display members on pacakge ID 4.
}

Ideally I want to get it so it will be a basic slider on the site somewhere, fading through all the members on specified membership ID.

Any help would be appreciated!
