how do I upload my member picture?

Go to 'My Account' and choose 'Edit Profile', then select the middle tab, called ‘Account Settings’. This is the picture that gets used to represent you on the site – your avatar. It’s currently called ‘picture’; when you’ve chosen your file, you upload by hitting ‘submit’ at the bottom of the page.

You also have an option to upload stills to your profile page - you'll find that on the 'User Profile' tab, next to 'Account Settings'. This will display stills inside your profile page.
