Unwanted Border

So basically I’m trying to render an image using the shader code mentioned here: http://www.jmonkeyengine.com/jmeforum/index.php?topic=4623.30.  It works relatively nice, except I commented out the Fog part of it.  What I want to know is why there are border lines appearing around the texture being rendered?

Here is a screenshot:

Here is the texture I’m using (don’t worry if the texture looks black because your viewing it a browser, if you download it the black becomes an alpha channel because it’s a png):

missing a blendstate or wrong settings ?

Yeah, sorry for the vague description.  Thanks for the help though, I figured it out.  I was using Paint .Net and it somehow messed up the alpha channel or something in the texture format.  I switched to Photoshop and somehow that worked.  Note to self: Do not to use Paint .Net  :D.
