 * Is it possible to force Photon to update thumbnails edited using [https://wordpress.org/plugins/crop-thumbnails/](https://wordpress.org/plugins/crop-thumbnails/)
 * Although the new thumbnails are saved correctly on the local server, Photon continues
   to serve those created automatically when the original image was uploaded.

 * Unfortunately, no… the only option to cache invalidate with Photon is to actually
   contact automatics, and they will invalidate individual images… seriously, just
   don’t bother with photon until Jetpack gets its act together, use cloudflare 
   or luminary or something.

 * As [@wpsmartcrop](https://wordpress.org/support/users/wpsmartcrop/) mentioned,
   that isn’t possible. However, contacting our support team to invalidate cache
   for individual images won’t help either.
    Photon doesn’t actually use any of 
   the thumbnails created by WordPress when you upload an image, and when you edit
   that image inside WordPress’ image editor or through a plugin. Photon only uses
   the original image, and creates several resized versions of that image:
    - A new resized version is created for each new thumbnail size used by your 
      theme.
    - A new image is created if your theme is responsive, and smaller versions of
      images are needed on smaller devices.
    - A new image is created if readers access your site from Retina or HiDPi devices
      with a higher pixel density. For those devices, you want to serve larger images
      when possible, instead of using an original thumbnail that may end up looking
      a bit pixellated on a Retina device.
 * I hope this clarifies things a bit.

 * Thanks Jeremy
 * I’ve had to disable Photon for the time being, as I need to control the crop 
   on some.
