* @help This plugin does not provide plugin commands.
*
* This plugin allows you to specify how often the image cache should be
* cleared, and what kind of images should be cleared. This can be used
* to improve memory usage on low-memory platforms, but will also result
* in more frequent loading delays.
*
* If not using the 'clear all' default option, and you have plugins that
* use their own custom image paths, list those paths in the Custom Images
* parameter to clear any images cached from those locations.
*
