iPhone Contacts displays wrong photo for every person

Hi everyone,

I've been living with this problem for years and I can't stand it anymore.

Almost all of the contacts on my iPhone have someone else's picture. Joe's face shows on Eric's contact page. Mom's photo shows up next to my boss' name, etc. Sometimes I delete the image, but it will just come back.

The odd thing is, everyone's picture shows next to the correct name in 'Contacts' on my computer.

I've followed every troubleshooting advice page I can find online. Switching the iPhone's 'Default Account' to iCloud or From My Mac makes no difference.

I wish I could just blow away all the contacts on my phone and resync with my computer, but this doesn't seem possible at all anymore.

I'm running iOS 7.1.2, and Mavericks.

Any solution would be greatly appreciated! Thanks in advance!
