Problem with NB Image Converter

I'm trying to convert one of the .nb files that I found (ftp.ppcgeeks.com/Apache/Misc Apps/Splash Screens/Earth.nb) to a .bmp file so I can use it as a background.

The problem is whenever I Save to .bmp it just saves the ImageConverter logo instead of the picture of earth? Is anyone able to convert .nb to .bmp successfully using this util?

If not does anyone have a .jpg or .bmp of this bootscreen?

Thanks!
