Study Curve

Go to your profile page and at the top next to your name you'll see a spot that says, edit your profile. Click on this and then look on the right side of the screen and you'll see a place to upload photos.
Click on the browse button and that will open a window to that will give you options about where you want to upload photos from. Once you find the photo you want to upload, just click the upload button and your picture will upload. I'm sure Juke, or someone else, can and will explain it better, but thought this might be enough to help you fiddle around and get a picture on your page.
