title: Issue with SameSite attribute with rails
body: <p>I've got an issue which is popping in the console of my web browser while I want to show a picture from Cloudinary.
  Exactly here is the message :
  <strong>Indicate whether to send a cookie in a cross-site request by specifying its SameSite attribute</strong></p>
  <p>Because a cookie's SameSite attribute was not set or is invalid, it defaults to SameSite=Lax, which prevents the cookie from being sent in a cross-site request. This behavior protects user data from accidentally leaking to third parties and cross-site request forgery.</p>
  <p>Resolve this issue by updating the attributes of the cookie:
  Specify SameSite=None and Secure if the cookie should be sent in cross-site requests. This enables third-party use.
  Specify SameSite=Strict or SameSite=Lax if the cookie should not be sent in cross-site requests</p>
  <p>I don't know where I can change this(SameSite set up) in order to allow my pictures to be viewed.</p>
  <p>Thanks</p>
