I've got an image, the same one in multiple courses multiple times.
We had put it in a repository with the plan to use the alias technique when it came time to change the image to a new one.
I duly updated the repository image (kept the file name constant), but the planned site wide update didn't take effect. I'm guessing people copied the file instead of aliasing it.
What options have I got other than visit each and every instance of it and manually change it over. Is there anything I can do site wide?
We are on MySQL and Ubuntu 14 with Moodle 3.3
Any ideas much appreciated.
