First off: Can't you find a different image? Why rip someone's image off their staff page and THEN ask for their help to code the PHP for it?
Second off: Spoon feeding, jeez man the answer behind this is actually common sense.
The solution: Make a table where it shows the users id, and the spot where they should be on the page.
Ex: Make a table called "staff_spots" with 2 columns: "user_id", "staff_spot"
In the user_id spot add the user's user ID and the staff should be on the page
Then pull it from the DB and put it to use.
Damien told me how he did this a while back.
Edit: You will need a 3rd column to hold the sitting waving standing etc but the idea is the same
