How do I add or change my profile picture?

1. From the topbar, click the My Settings button. The button appears as a round profile image. 
   Note: If you have not added an image to your profile, the profile image will appear as a blank silhouette.
2. A drop-down menu will appear. Select My Settings.
3. If not already visible, select Manage Profile from the My Settings sidebar at left.
4. Click on the blank silhouette or the current profile picture and select a profile picture to upload from your computer. 

Note: Pictures files must be a jpg or png. To ensure a centered profile picture, the image should be square. For best results, size your picture at 400x400 px.
