What are these pictures of food all about?

When you sign up to Win a Dinner you are given the option to sign up via social media, in which case your avatar becomes the one you use for Facebook or Twitter, or to upload a photo of your choice.  If you do neither, you are allocated one of our house avatars.  These are drawings of our favourite dishes against a coloured background.  You can change your avatar when you are logged in by clicking on it (top right) and selecting "Account".
