Error with image file upload

[Mythotical]

I have added the file image upload code while I wait on a response regarding file image upload to database.

Anyway, here is the code I'm using thus far:

PHP Code:

if($_REQUEST['do'] == 'saved')
    {    
    $upload = new vB_Upload_Image($vbulletin);
    $upload->image =& vB_Image::fetch_library($vbulletin);
    $upload->path = './'.$options['sponsor_imgpath'];
//    if (!($upload->process_upload($vbulletin->GPC['img_file']))){
//        eval(standard_error(fetch_error('there_were_errors_encountered_with_your_upload_x', $upload->fetch_error())));
//    } 
    
        $sql = "INSERT INTO  `" . TABLE_PREFIX . "sponsors`
                (`title` , `url` , `image` , `description`, `inactive`, `img_file`) 
                VALUES (
                '" . $db->escape_string($vbulletin->GPC['title']) . "',
                '" . $db->escape_string($vbulletin->GPC['url']) . "',
                '" . $db->escape_string($vbulletin->GPC['image']) . "',
                '" . $db->escape_string($vbulletin->GPC['description']) . "',
                '" . $db->escape_string($vbulletin->GPC['inactive']) . "',
                '" . $upload->process_upload($vbulletin->GPC['img_file'] . "'
                        )");

$vbulletin->db->query_write($sql);
print_cp_message('Sponsor Added.', 'sponsors.php', 5);
    } 


EDIT: Fixed previous error, new problem.

When I click submit, I get the following error:

Database error in vBulletin 3.6.8:

Invalid SQL:
INSERT INTO  `sponsors`
				(`title` , `url` , `image` , `description`, `inactive`, `img_file`) 
				VALUES (
				'Download Now',
				'www.download.com',
				'',
				'blah blah blah again',
				'0',
				';
