Once activated, this addon acs as a proxy between the user and external image resources.
|
||||
If external images are to be shown, like avatars or embedded images, the server retrieves the image and the local link is sent to the user.
|
||||
By using this proxy, the server hosting the original image cannot retrieve personal information of the user like the IP address, User Agent or Cookies.
|
||||
However, the remote server will be able to track the IP address of the server hosting the friendica installation.
