 * I have tried Photon but turned it off a long time ago.
    Today I had a very high
   serverload, so much so that it turned into a big problem.
 * Looking i my logs a found more that 45.000 hits with Photon in them, like:
 * “GET /blog/wp-content/uploads/2015/07/Laila-B-Thomsen%E2%80%8E%E2%80%8E_28-07-
   2015%E2%80%8E.jpg HTTP/1.0” 200 428221 “-” “Photon/1.0”
 * I really need to get Photon to stay away, what can I do??

 * That can indeed happen, as anyone can use Photon to request an image, even if
   the site hosting the image doesn’t use Photon. For example, I could force Photon
   to query and cache an image from Google’s homepage, like so:
    [https://i0.wp.com/www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png](https://i0.wp.com/www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png)
 * This will only generate one request, though, as once the image is cached Photon
   won’t need to query the original source to return the image.
 * However, if you have multiple images on your site, if the image is available 
   in different sizes, or if someone uses Photon to request these images on your
   site, Photon will need to make multiple requests to cache each image, and each
   resized version of each image. That may add up to a significant amount of hits.

 * If you’re not using Photon on your site, and if you don’t want Photon to be able
   to make any requests to images on your site, you can block the `Photon/1.0` User
   Agent in your `.htaccess` file, as explained here:

 * I hope this clarifies things a bit.
