Can't get box art to show up in theme for NES

[ThePlayer]

I can't get the boxart to show up in the theme, I'm using the NES theme by Cosmo on a PC system.  The wheel art and videos are showing up perfect, only the box art won't show.  I set box art to yes, and pointed the flyer to where my box pics are (c:\emulator\NES\boxart).  All the box pics match the rom file name.  Any ideas of what I am doing wrong would be very appreciated.
Thanks

I would suggest post your config file.

Never mind, I thought I was supposed to use the flyer section for the boxart, I just figured out I needed to make a boxart artwork section
