To remove the black bars from your photo, click "Change Photo" and then click "Edit Your Current Photo". Then drag the outside corners of the photo sizer box inside the black lines on your photo. When you have the box where you would like, click the blue "Done" button. Be sure to save your work by clicking the purple "Save My Work" disc icon from the toolbar menu or clicking the pink "Save and Next" button on the lower right side of your account. Once you have done this, click "Preview" and your image should be there, just the way you cropped it.
