Donald, to explain what I did, so you can do it yourself if this ever happens again:
Go to the image page and add in the Wikitree ID# for the profile you WANT there (in this case it was Pretty-194).
Scroll down to where it says People & Things in the Image:
Then to the part that says: Add person or free-space profile: [there is a box thing here, to paste or type in the ID#]
Scroll down to "SAVE CHANGES TO IMAGE DETAILS" and click that.
Scroll back up to select set as primary or background image and click the little check box there. Then click the "Set" button. (In this case it was set as PRIMARY image.)
Then, if you do NOT want the image on a particular profile, you scroll back to where you add the Wikitree ID# and select to REMOVE an ID# (in this case it was George Baker-Hill I removed from the image). This leaves the image on the profile (or profiles) where it is wanted to be.
I hope this helps.
