If you connect your Slack account, we'll pull in your profile photo from Slack and automatically keep it synced.
We currently don't support uploading a custom photo for email user accounts. However, like many sites across the web, Tettra does support Gravatar. Just upload your desired profile photo and associate it with the same email address that you use to sign into Tettra and we'll use that as your profile photo. You can create your Gravatar here.
