As a member of a site's community of collaborators, it's recommended that you invest in adding a profile image. This will make you easier to identify visually and help differentiate you from other users.
When signed in, you access your profile by clicking on 'My Profile' in the upper right corner of the page. When the drop down window appears, click on 'Profile' below your user name.
Click on "Add image" to upload a profile picture. If you already have a profile image click "edit image" to change it. You can upload an image directly from your computer or get one from the web.
Your profile avatar and a link to your profile page coincide with all comments you make across the site.
Note: Administrators can remove your profile image if they deem it inappropriate.
