How do i put my own picture on my profile and not one from the list
First you take the photo you want to use and make it no larger than 48x48 pixels. Save it. Then open your personal profile. Down where the avatar space is, there is an 'edit' link. Clicking on this will open a window with a 'custom avatar' option. Click on that and you'll see two options - one for a url for the custom avatar and one to upload one. Click on the upload choice and you'll be able to browse for your avatar and upload it.
