How do I post it under my name?
You will first have to save your map image to your computer, then upload it to the web. Make sure you choose the small size map. Some people upload their photos to free image hosting sites like Flicker or Webshots. I upload them to my own web space.
After your photo is uploaded, copy the URL by right clicking with your mouse.
The go to My Controls (upper right of this page). On the left is a link that says "Edit Signature.
Click on the icon to add a photo. Then paste your URL into the box that appears.
Save your changes, and that is it.
