My WordPress installations that have no timthumb scripts get this error at the top of the plugin scan page when I run the scan.
Warning: Invalid argument supplied for foreach() in /home/...../wp-content/plugins/timthumb-vulnerability-scanner/class-cg-tvs-plugin.php on line 115
I know... if there are no timthumbs to scan for why bother? Well, because you don't know if there are any until you do.
I don't think the previous version behaved this way.
Thanks again for a great plugin.
