function fileUpload($max, $module_dir, $file_type, $msg){
        //Retrieve file details from uploaded file, sent from upload form
        $file = JRequest::getVar('image', null, 'files', 'array');
        if(isset($file)){ 
                //Clean up filename to get rid of strange characters like spaces etc
                $filename = JFile::makeSafe($file['name']);

                if($file['size'] > $max) $msg = JText::_('ONLY_FILES_UNDER').' '.$max;
                //Set up the source and destination of the file

                $src = $file['tmp_name'];
                $dest = $module_dir . DS .$filename;

                //First check if the file has the right extension, we need jpg only
                if ($file['type'] == $file_type | | $file_type == '*') { 
                   if ( JFile::upload($src, $dest) ) {

                       //Redirect to a page of your choice
                        $msg = JText::_('FILE_SAVE_AS').' '.$dest;
                   } else {
                          //Redirect and throw an error message
                        $msg = JText::_('ERROR_IN_UPLOAD');
                    }
                } else {
                   //Redirect and notify user file is not right extension
                        $msg = JText::_('FILE_TYPE_INVALID');
                }

                $msg = "<script>alert('". $msg ."');</script>";
        }
