How make it dynamic?

Attempted;

var slideimages=new Array("getpics.php")

//getpics.php...

function returnimages($dirname="path/to/images") {
   $pattern="\.(jpg|jpeg|png|gif|bmp)$";
   $files = array();
   $i = 0;
   if($handle = opendir($dirname)) {
       while(false !== ($file = readdir($handle))){
               if(eregi($pattern, $file)){
                 echo("'$dirname/$file',\n");
                 $i++;
               }
       }

       closedir($handle);
   }
   return($files);
}
returnimages(); 

Any help here would be great!

Edit: Ok, cool fixed!

echo("$dirname/$file,");
