Manual server preview refresh

[TheArmyGuy]

Honestly the server preview at http://www.blockland.us/browse.php only refreshes once every ~3 days for my server, but I REALLY like the isometric images it makes. I know of /setpreviewcenter but is there also a command to force an update? If not, is it possible to make an add-on/script that does?

Thanks, locking.
