How to change display picture on other profiles?

I closed my account but forgot to remove an image (Coat of Arms) that I had added on a number of profiles. Unfortunately, it proved to be the wrong one. It seems like I cant replace it with the accurate family crest now. Is there any pro here that can help me fix it? I have e-mailed the owners of these accounts but they do not seem to be active here nomore /Wic
