Extract wallpapers from macOS installation CDs or disk images without installation
I admit this answer may be a little presumptuous of me.

Assuming I'm reading between the lines correctly, if all you're wanting to do is grab a copy of the macOS desktop background image from an earlier version of macOS, these are readily available from many websites. 

For example, you can download 5K versions of these images at Every Default macOS Wallpaper – in Glorious 5K Resolution.

[UPDATE}

After discussion with the OP it was established that what they were after were all the original desktop background pictures from Mac OS X versions 10.4, 10.5, 10.6, 10.7, 10.8 and 10.9. 

On the off chance anyone else will want/need these, I have uploaded a .zip file containing all of these in their original unaltered state. After clicking on the link just click on the button representing the download option you want (slow v turbo).
