I might even add my pic one day.

If the picture is too big it won't work.

I am not sure what instructions you are following - so I will add these here:

1. signin
2. go to MY ACCOUNT
3. click MY PROFILE
4. click PERSONAL INFO
5. fill in as much INFO as you care to in the ABOUT ME box.
6. Upload your photo in MY IMAGE - click the BROWSE button - find you photo file on your PC - highlight it - click OPEN
7. click SAVE button

you then should see your PROFILE updated.
