Good, Add-on, but there is one Problem.
Google now support hd pictures up to 720x720px.
So they are synched to Android as well in this resolution.
No I found out, that some of my pictures were scalled back to 96x96px. The Cause for this is the synching with TB. There the pictures are dwonsized. I don't know if this is a problem of TB adresse book or the add-on. But there could be the option to turn off picture syncing. Then the Problem would not exist.
gContactSync downloads photos from Google and does not scale them. Thunderbird is responsible for displaying the photos.
gContactSync has a preference to not download photos. Go to Menu -> Options -> Options -> Advanced -> Config Editor. Type "photos" in the textbox and change getPhotos and setPhotos to false.
