AntiContainer is an extension and framework to DownThemAll! which allows the user to download resources that are normally hidden behind container pages.
For instance almost all so called "one-click" image hosters, such as imagevenue, use such container pages. AntiContainer enables DownThemAll! to download the actual images there instead of just the page.
AntiContainer uses small "plugins" that will handle the specific container pages. A set of plugins is provided with the installation, but it is fairly easy to write new plugins, too.
