I have a private Microsoft Visual Studio Team Foundation Server (Version 15.117) running in my network.
When I look at the history of a Git project (like https://tfs.local/tfs/»Collection«/»Project«/_git/»Repository«/history?_a=history) in the author column there are avatars shown.
TFS automatically(?) retrieves authors Gravatar image through URL https://tfs.local/tfs/»Collection«/»Project«/_api/_common/IdentityImage?id=&email=»none%4example.net«%3E&defaultGravatar=mm&__v=5 that 302 Found redirects to https://secure.gravatar.com/avatar/»md5-hash«
With this behaviour, Gravatar (and possible entities in between) know my project and repository names, which is not acceptable.
How can I prevent the webinterface to display Gravatar (and other 3rd party) images? Locally upladed images are okay.
(Visual Studio 2013 GitHub avatar not being displayed is not related as this is a setting for Visual Studio and "Enable 3rd party source" already is un-ticked)
There is no such setting in TFS to prevent TFS from showing images. I've submitted a uservoice at website below, you could vote it:
