Adding an image to your profile can be done in one of two ways:
Self-Edit Links
If the event organizer has sent you a self-edit link via email, you can use that to access your profile on your desktop or mobile and add your photo there.
Event Space
After logged in the Event Space, you can edit your profile and add your picture by navigating to the Attendee Dashboard (upper right profile icon) and clicking on Edit Profile.
If you are having any trouble uploading your image, please send the image to Support and indicate your name and the event you are attending. We would be happy to upload it for you.
