Briar isn’t the kind of app you necessarily use every day and, in fact, it positions itself as a something used by activists. That being said, it’s really useful that there’s now the ability to send images to other users.

I’ve tested the feature (which requires both parties to be on v1.3) and it works well.

The Briar Project released version 1.3 of its Android app today. Thanks to support from eQualit.ie, this release adds several new features that have been requested by many users over the years.With today’s release, users can upload profile pictures that will be visible only to their contacts.Lots of people have asked for a way to send images via Briar. We listened! This release adds the ability to send images in private conversations. Images are still heavily compressed, so high resolution images might show pixel artifacts.
