I am looking at your profile and you have a picture posted. Do you mean you are trying to upload an avatar such as the one below my name on the left in this message?

What happens when you try to post your pictures? Do you get an error? If so, what does it say?

The Gallery and My Models photos are pretty self explanatory. Click Add Photo. State a title for the photo. Give the photo a description. Click Browse to locate the photo on your computer. Select the photo on your computer and click Open. Now click the Add Photo button and wait for your photo to upload and be displayed.
