July 2018 Google told us they would be changing the referral source URL from Google Images from https://www.google.com to https://images.google.com but that isn’t going to happen anymore. Google updated their post last month I believe saying they will not be going through with this change.

At the top of the post is now reads:

Again, I think Google changed this last April but the update is not labeled with a timestamp, so I am not 100% certain when Google decided not to go through with this.

For those who have already updated their analytics tools to handle it, you can undo that change – sorry.

Hat tip to AJ Kohn for spotting this:
