Thunderbird doesn't support
My contacts address book is provided by Apple iCloud, of which I have added contacts with avatars for every contact I've received legitimate emails from. However, Thunderbird fails to render these avatars. The result looks like the attachment. Perhaps Apple is using HEIC for them?

Unfortunately Thunderbird (Mac) CardDav address books don't display contact photos from Contacts.app Even if you succeed to add a photo while editing a contact in the CardDav address book in Thunderbird, it will disappear immediately when you click the "Save" button, no matter which image format you choose. Thunderbird and macOS address books never liked each other very much......
I did notice Evolution Mail does show the avatars in their Contacts view correctly; however no avatars in their mail view, and their mail view does not seem aware of saved contacts, as it always prompts to save addresses as new contacts.
However, all other clients I tried, didn't have any address book avatar support; Geary, Mailspring, Vivaldi.
Maybe the Evolution Mail code can be referred to by those interested.
