Pessimization of the site when translating media content to cdn servers?

Question

Search Engine Optimization

Now the sites have links to media content from my domain. But if let's say I transfer all the content to the sdn server (i.e. the urls for media files will be from another domain), how will this affect the position in the issuance of Google and Yandex?
Those. Poidee in the eyes of the search engine, I will cease to be the owner of photo and video materials.

Answer 1

I specifically asked a Google representative about images on the CDN - https://youtu.be/UfpskkLpC30?t=50m1s (question at 50 minutes).
On a promoted site with such an implementation, I don’t notice any problems in promotion (including in Yandex).
