Mambo and SEF Advanced??

If anyone can help, i use SEF Advanced a component for Mambo... the below code is the example extension file for integrated components to utilize SEF URL's within SEF Advanced. I dont know gallery2 side well enough to have the correct placement of code...

<?php
/**

* Place this file (sef_ext.php) in the main component directory
* Note that class must be named: sef_componentname

class sef_example {

	/**
	* Creates the SEF advance URL out of the Mambo request
	* Input: $string, string, The request URL (index.php?option=com_example&Itemid=$Itemid)
	* Output: $sefstring, string, SEF advance URL ($var1/$var2/)
	**/
	function create ($string) {
		// $string == "index.php?option=com_example&Itemid=$Itemid&var1=$var1&var2=$var2"
		$sefstring = "";
		if (eregi("&amp;var1=",$string)) {
			$temp = split("&amp;var1=", $string);
			$temp = split("&", $temp[1]);
			$sefstring .= $temp[0]."/";
		}
		if (eregi("&amp;var2=",$string)) {
			$temp = split("&amp;var2=", $string);
			$temp = split("&", $temp[1]);
			$sefstring .= $temp[0]."/";
		}
		// $sefstring == "$var1/$var2/"
		return $sefstring;
	}

	/**
	* Reverts to the Mambo query string out of the SEF advance URL
	* Input:
	*    $url_array, array, The SEF advance URL split in arrays (first custom virtual directory beginning at $pos+1)
	*    $pos, int, The position of the first virtual directory (component)

	*    Note that this will be added to already defined first part (option=com_example&Itemid=$Itemid)
	**/
	function revert ($url_array, $pos) {
		// define all variables you pass as globals
		global $var1, $var2;
 		// Examine the SEF advance URL and extract the variables building the query string
		$QUERY_STRING = "";
		if (isset($url_array[$pos+2]) && $url_array[$pos+2]!="") {
			// component/example/$var1/
			$var1 = $url_array[$pos+2];
			$_GET['var1'] = $var1;
			$_REQUEST['var1'] = $var1;
			$QUERY_STRING .= "&var1=$var1";
		}
		if (isset($url_array[$pos+3]) && $url_array[$pos+3]!="") {
			// component/example/$var1/$var2/
			$var2 = $url_array[$pos+3];
			$_GET['var2'] = $var2;
			$_REQUEST['var2'] = $var2;
			$QUERY_STRING .= "&var2=$var2";
		}
		// $QUERY_STRING == "var1=$var1&var2=$var2";
		return $QUERY_STRING;
	}
