$pattern = "\/xcart";

Is that assumption correct?

Yes, you are correct. /xcart would become /xcart/upgraded. Of course this will append both leading and trailing content as well.

If your not too familiar with regular expressions:

You also correct in assuming x-cart does a string compare for the full path, within the func_get_thumbnail_url function in include/func.php using $xcart_dir. (4.0.x)

$cmpfunc = (X_DEF_OS_WINDOWS ? 'strncasecmp' : 'strncmp');

...

			if (X_DEF_OS_WINDOWS) {
				$thumbnail_info['image_path'] = str_replace('/', '\\', $thumbnail_info['image_path']);
			}
			if (!$cmpfunc($xcart_dir, $thumbnail_info["image_path"], strlen($xcart_dir))) {
			# image_path is an locally placed image
				$url = $current_location.str_replace("\\", "/", substr($thumbnail_info["image_path"], strlen($xcart_dir)));
				return $url;
