You need to add plguins/content/DGcontactinfo/includes/timthumb.php to the "Allow direct access to these files". This will let the thumbnail script to load.
Then you need to set the "Protect against common file injection attacks" option. When this option is enabled we block any request which passes a URL as a page parameter. Since the image is passed to timthumb.php as a URL in a page parameter it results in the request being blocked. Disabling this option will allow timthumb.php to work BUT it also degrades the security of your site.
After these changes please remember to click on Save & Create .htaccess.
SECURITY WARNING! While these actions will let your thumbnail script to run they also seriously degrade the security of your site. TimThumb has a long history of serious security vulnerabilities which, a few years ago, caused millions of WordPress sites to be hacked. We DO NOT recommend following these instructions and let a potentially vulnerable script to run unchecked on your site. We DO recommend looking for a different plugin which doesn't require you to degrade the security of your site to work.
