I'm loving Yosemite, but this one deal with Contacts.app has me stumped: I regularly assign images in Contacts.app to people with whom I exchange a lot of email. When email has no image, I add the address to Contacts, find an image on the web, drag it into the contact card, and the image instantly appears in Mail.app. But here's the thing: In Yosemite, after adding a new email address to Contacts.app, sometimes an image of the person appears inside the circular image field automatically -- before I've located and added one. I have no idea where those images are coming from. Now, this would be a good thing (less work for me) if those images also showed up in Mail.app, but they don't. Furthermore, when I click on "Edit" to edit the "phantom" image, the image disappears as if there were no image there to begin with. But when I dismiss the edit window, the "phantom" image reappears. (And yes, the images do match the persons. So, clearly the images are being pulled from some sort of valid source.) I'm not sure if this is a new feature that's simply not yet fully baked, or what Clearly, Contacts.app is finding these images somewhere, but despite finding them, it's not properly pushing the images to other apps, like Mail.app. Has anyone else observed this?
