Placing logo in the header help

Hi, I am trying to customize the power_user skin by adding a logo on top. I have the logo in the images dir, I have added the image token to the files_user.conf file, and I have added img tag with my custom token to the header.html. When I type the IMG_LOGO token directly into the browser URL, my logo comes up, but on the actual page the IMG_LOGO is replaced with the word "none". Any idea what am I doing wrong?
Thanks
David

worked it out

Sorry I was confused, I was under the impression that tokens always have to enclosed in "pipes" so I was using <img src="/|IMG_LOGO|">, but this dosn't work. So when I use just <img src="IMG_LOGO"> that works. Not sure why it is like that.
