This is what I see:
Give me a few minutes and I'll figure out why.
Okay, I know the problem. I went and took a look at your sig and saw that there wasn't a single thing suggesting there should be a picture there.
To get a picture in your sig, you'll need to upload the picture you want to photobucket or imageshack. I use photobucket, but imageshack doesn't require you to have an account.

photobucket - http://photobucket.com/
Once you've uploaded the photo, select the code for IMG on photobucket or hotlink for forums(1 or 2) on imageshack. Copy the code given.
Next, go to edit your signature, and paste the code wherever you want the image to be in your sig and then click "Save Signature" and you're done. :3
