It's only happened once (a long time ago), but if there is a security-related bug, we'll let you know - if you've signed up for update notifications (extremely low-volume)

To encourage everyone to actively look for bugs and report them, I'm currently offering a $5-$50 bounty per bug you find and report before anyone else! Most bug reports are firmly in the $5 category, but a security hole or memory leak could net you $50 for the one bug. Payments sent via PayPal. All class libraries whose names start with ImageResizer are eligible. Email bug reports to support@imageresizing.net. Only the latest version of the product is eligible; offer starts once V3.1 is published.
