I actually got it this way. I went to os9 and drag the file out of the Appearance interface. When you drop it to the desktop, it shows up as a scarpbook file. Then I used Graphic converter to make it into a jpg file. I now have it on my OSX background.
I should habe made it clear that OS9 is not installed on my new mac. Also I am speaking of the default desktop picture of the Happy Mac face on the blue backdrop, called Mac Deafult picture on mac os9.
