Thank you for this add-on, it's great and very useful.
Everything working fine, until working with local address book. In my scenario i have to use remote address book connected with CardDAV add-on named "CardBook" - https://addons.mozilla.org/ru/thunderbird/addon/cardbook/ .
That add-on is not extend bilded-in address book, but provides another one. After it being synced, no photos shows with Display Contact Photo add-on.
Is it possible to extent functionality to support CardBook plugin?
