At this time, you need to use Thwapr on the desktop (Mac or PC) to set or change your picture profile.

Login to Thwapr and go to "My Account".

Select "Change Picture" and upload a square image for your profile - JPEG, GIF, and PNG supported.

Your profile picture will appear now on the desktop, mobile web, and in the app.

Note: the plan is to let users set or change their profile picture in the app too, please stay tuned.
