My profile photo is correct, but someone else's photo started to display for my record when sending email or searching for myself in Yahoo Mail. I would see the wrong photo when I type my email address in the TO field when sending an email to myself. I would see the wrong photo when I search for myself in the Yahoo Mail search box.
I deleted my contact record. I had created a contact record for myself so I could quickly send messages to myself when I want to save information in Yahoo Mail. I still saw the wrong photo.
SOLUTION: I cleared my cache and re-opened the browser. My correct from my profile now displays.
I think the key is to make sure the correct photo is in your profile. Delete any contact records you have for yourself. Then, clear your cache. I'm going to re-add my contact record.
I suspect other email recipients were not seeing the wrong photo. Just me.
I'm publishing this post, because Yahoo Answers does not have the correct answer posted and I can't figure out how to post the correct answer in the thread.
