Friend's profile picture not showing in Mac mail messages

I don't think it's a local problem because most of my contacts have profile pictures that are not on my local drive or any drive for that matter yet there picture still remains within the contact profile. For example, I have Apple's customer service number in my contacts and I used he Apple logo as the profile picture. That logo pic is no longer on ANY of my hardrives or on my phone yet it appears within the contact profile. That's why I feel something is fishy here.

Yes. In fact BOTH old and new email address are in his contact profile. So, in the begining there was only one address, his old address which I learned he doesn't really use anymore. So then I added the new one but kept the old one just in case. Here is the order I kept them:

1) old email

Then, once I learned of his new email:

1) old email

2) new email

After I learned the that the old email wasn't really used anymore, I switched the order:

1) new email

2) old email

I'm not sure if the order in which the email addresses are listed matters but I thought I'd mention it in case it does

Ok, I have an update: The issue regarding the profile picture for my friend showing has been solved simply due to Apple's recommended updates from the app store. Now there's a new related issue though. My friend, who we'll call "Dan", has his full name spelled out when I receive an e-mail from him which is different from how I have it in my contacts. I have him listed as Dan, not Daniel (which is what shows up when HE e-mails or replies to me). I checked to see if he was perhaps e-mailing or replying to me from a different e-mail address but he's not. So shouldn't his name be spelled as I have it listed in my contacts?

I'm not sure I understand this. Can you elaborate a little more? I checked this out and it just lists people I've e-mailed. So how does that solve my issue?

I looked in that list and MY spelling of his name is the only one that shows up.
