Hey Mary -
Instead of just removing the photo - click on it and scroll down to "Edit Photo Details".
All you have to do is click "remove from photo" for the person - and then add the wikitree ID# (e.g. Jones-1437) for the correct person.
Then, press the "Save Changes to Photo Info" button to complete the edit.
Also - I noticed that you did not crop the photo, which is why it appears so small up in the top left corner. You can crop a .jpg photo easily in MS-Paint so that just the photograph appears (and not all of the extra white space). Let me know if you need instructions on how to do this.
