Ok. So when you're in the mini-profile this code will make it so that only the staff's image shows. The text for that rank wont display at all!

It wont affect the members!

Go to:
=> Mini-Profile Template
Where you have {rank} or something like that.

Put this instead:

<script>
var a = /(Administrator|Moderator|Global Moderator)/;
var rank = '{rank_name}';
if(rank.match(a)){
    document.write('{rank_image}');
}else{
    document.write('{rank}');
}
</script>


Edit the red part with the 'staff ranks'.

To add more add another line ( | ) then the name of the rank. That should then do what you want!
