how to covert OFC(drupal API "ofc_api") SWF OBJECT TO IMAGE

step1 : sites/all/modules/ofc_api/php-ofc-library/ofc_upload_image.php

Add following  code:
// default path for the image to be stored //
- $default_path = '../tmp-upload-images/';
+if( ! $_GET['defaultPath'] ) {
+    $default_path = '../tmp-upload-images/';
+} else {
 +   $default_path = $_GET['defaultPath'];
+}
