Ok there are a couple of problems.
Problem number one is that the link doesn't work. To get the correct link you have to right click on the image, click properties and copy the url - http://www.animecubed.com/galleries/naruto/pics/nto065.jpg
Problem 2 is that the picture is huge, way too big for a signature, so you wouldn't be able to use it even with the correct link. I saved the picture and resized it to the maximum height that you are allowed in a signature (200 pixels), then uploaded it to my photobucket account (www.photobucket.com). Using the IMG tags around the url that photobucket provides I get this:
If you want to use this in your signature add the following to the appropriate box in your preferences - [IMG ]http://i39.photobucket.com/albums/e181/more_ncis_now/Naruto/naruto.jpg[/IMG ] (take out the spaces between IMG and ] to get the code to work)
Alternatively you can upload the picture to your own photobucket/imageshack account using the url - http://i39.photobucket.com/albums/e181/more_ncis_now/Naruto/naruto.jpg - and then add to your signature box putting the IMG tags around your own URL from photobucket/imageshack as follows:
