This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
What does it do?¶
The extension adds a link to the clear cache menu (flush caches) for editors and admins. On click the processed images will be deleted like the button in the install tool would do. Afterwards the frontend cache is cleared automatically.
For editors this link is useful after the replacing of images or files in the filelist.
The link clears the frontend caches, too.
Just install the extension and reload the backend. The link will appear in the clear cache menu.
