I have this code making a random image:

public function RandomImage( $strLeftDirName ) 
   { 
      if ( !is_string( $strLeftDirName ) ) 
      { 
         return false; 
      } 
      $left_dir = DataObject::get_one("Folder", "Name = \"$strLeftDirName\""); 
      $randImg = ( $left_dir->ID ) ? DataObject::get_one("Image", "ParentID = $left_dir->ID", true, "RAND()" ) : false; 
      return $randImg->Filename; 
   }

But how would I make it a random background image on a div?
I want to be able to apply it to my header if possible?

Apply it via inline CSS on the element. e.g.:

<div id="header" style="background-image: url($randomHeaderImage)">
<h1>My website</h1>
</div>
