Didn't see these on here also for those who are uploading from her service and want to make sure they can't track back to your account
The link listed is "Where from" is stored as an extended attribute named "com.apple.metadata:kMDItemWhereFroms" on the file in the file system - it is not actually saved within the .jpg file itself.
You can remove it by opening Terminal.app and running the following command:
xattr -d com.apple.metadata:kMDItemWhereFroms filename.jpg
where filename.jpg is to be replaced with the actual path and name of the file. The easiest way to do that is simply to write the first part of the command, and then drag the .jpg file into the Terminal.app window.
