Rated 1 out of 5 stars
It doesn't show contact photos at all. When I click on the placeholder where the contact photo should go, I receive an error message that states "Please add this contact to your address book (click the star next to 'from') before trying to edit the photo".
However, the contact's photo is invariably already inserted in the contact's details in both my Thunderbird and Apple contacts (which are synced on my computers). And, for what it's worth, Apple Mail invariably shows the photo.
Awaiting a reply from the developer…
