In Campus Square, click on the Student Lounge tab at the upper right. When the next page displays, click on the Student Introductions link at the left. Next, click on the Introduce Yourself to the Class tab. You'll then see a title box and a "Your Introduction" text box to introduce yourself. Underneath, you'll see the "Upload a Self Portrait" section underneath the text box. Choose the Yes option, and on the next page, you'll be able to browse your computer to upload your portrait - it should be a JPEG.

Hope this works for you!
