I think you should have done it in reverse, in other words, add Alexander-4864 to the picture then remove Alexander 4865.
But now you may not be able to recover the photo, unless you go to your contributions list, find where you added the photo and click on it, see if it will come back up. Then add the correct Alexander profile to it. See if that works. (It just depends on how many days ago you removed it and if it is still in the system).
