For more information, please see plugin home page and FAQ PAGE Very important: Read before use and install! Varnish, Lighthttpd, and other �cache� services is not 100% compatible with this plugin � probably only if cache is disabled for all images. CDN images will not be redirected and no watermarked (if they are served correctly) � so, clearly, this plugin is suitable only for standard installation and for CDN with custom htaccess configurable by webmasters. CDN users must ensure that the images served by the CDN�s server may be manual updated or have expiration period. Beware of those who use the Jetpack. CDN wordpress (Photon) never expire, and the lowest WP-PICShield version that allows Photon to take pictures correctly is 1.8.9.d ! If you are unsure, do not use this plugin. Photon Cache can not be updated, watermark images remain forever (unless you change the images path or filename)
