Think the question was how to post one, not how to make one
Firstly you need your signiture picture.
Then you need to find a file hosting site such as
www.photobucket.com or
www.imageshack.us
Get your picture hosted and find the direct link to it (they'll tell you after you've uploaded it).
In your profile add the link to your signiture and add BBCode .
Make sure the boxes "Always attach signiture" and "Always allow BBCode" are checked in your profile.
Your next post should contain your signiture including picture
