    Please can you remove the following image from photon for me.

    I asked a few weeks back and you removed it then, but I failed to understand that it would regenerate if the image link in the article remained, so I have deleted that too.

    Thank you.

    Can you confirm: are images hosted on photon CDN discoverable by search engines directly or only through searching the website from which they originate? (i.e. if I remove images from my site, is it possible that they can still be found on photon CDN later and linked back to my site?)

    The image in question was (I believe) an embedded image from a newspaper who had a license. Usually embedding like this is acceptable, but if copies are created in a CDN then that may infringe copyright. Does photon CDN cache embedded images?

    The page I need help with: [log in to see the link]

    Hi there

    I replied in your other thread, but since you asked a few extra questions here:

    Can you confirm: are images hosted on photon CDN discoverable by search engines directly or only through searching the website from which they originate? (i.e. if I remove images from my site, is it possible that they can still be found on photon CDN later and linked back to my site?)

    Images will only appear in search results if they are displayed on a website. However, if a search engine has previously indexed an image which is later removed, it may still appear in search results until the search engine crawls that site again.

    Does photon CDN cache embedded images?

    Yes, if an image is served from Photon then we will cache the image on our servers. We can remove images from the cache, but as mentioned previously, if the Photon URL is visited again and the original image still exists, then the image will be cached again.

    Hope that helps! Let us know if you need anything else.

    One more consideration is that even if an image is removed from a site, the image URL may still appear in the site’s image sitemap.

    Having said that, Photon URLs include a canonical header that asks search engines to index the source image URL instead of the Photon URL, so in theory the Photon URL should never be indexed by search engines.
