Go up to the top of the page, to Profile. Once you're on the profile page, scroll down to the bottom and you'll see the Avatar Control Panel. Set up a small photo of your Mandy, no more than 180 pixels square (use Photoshop or some other graphic manipulation software) and place it on your computer desktop. Then click on Choose File and select the one you've created. It should then become an avatar for all of your posts. Lots of luck and welcome!
