To add new personal photos to your profile, click on the image in the top right of each page of the Site and then on "Manage Photos". Click on the button to add the photo, choosing the photo directly from the gallery or taking a new photo.
Also, from the section "Manage Photos" you can change the photo to associate with your profile using the button on the left. We remind you that only users who have uploaded their own photo as a profile picture will be visible in the search results.
