Changing trophy image postbit

I want to change the trophy image in the postbit for another one.

Where can i find the url to change the location?

Rewrite the image is not the good solution, because the image is being used for different places in the script.

check PlugIn "ibProArcade: Crowns in Postbit" for

$crowns = "<img src='arcade/images/trophy.gif' alt='".(count($champs["$post[userid]"]))." Highscore".$extra."'><br />";
