I imported user photos to the thumbnailPhoto Active Directory attribute. I ran a full user profile synchronization. Then, I ran the Update-SPProfilePhotoStore PowerShell command as described here. Also, "show in the profile properties section of the user's profile page" is checked.
The photos appear in the user profiles and the organization browser, but not in the People Search results.
I'm running SharePoint Enterprise 2010 with the February 2012 CU.
How can I make the photos appear in the search results?
