install mac os x leopard from dmg?

I don't know how to install mac os x 10.5 leopard from a dmg i bought a retail copy of leopard when it came out to keep a backup of the disk i made a dmg file from the disk to still be able to install leopard without the disk if i were to lose the disk. I lost the disk 2 years later. but i still have the dmg file what should i do to install leopard from the dmg file. I'm going to install mac os x 10.5 leopard on my ibook g4 (july 2005 model) with ram of 768mb1.33 Ghz PowerPC G4. Can anyone tell how to install mac os x 10.5 leopard from a dmg file. I'll give 10 points to who ever answers.

iBook, Mac OS X (10.4.2), iBook g4 2005

You can't install it from a .dmg. A dmg has to be mounted to be "seen" and it won't mount unless there is a system running, but then you have to unmount the DMG in order to reboot and then the mounted image is gone when you need to boot from it, etc. Basically you cannot boot from a DMG.

You will need to use the dmg and Disk Utility to burn the files onto a DVD.

Unless you have access to a Mac OS X Server box, you'll need to get and use a DVD burner.

You will have to burn a DVD on another machine.

The general rule is G4s cannot boot to USB. That said, you can find discussions here to the contrary but I think USB booting is by far the exception for G4s and would not assume it would work. Booting to Firewire is what is recommended for PPC computers running OSX.

If you still had the dmg them why did you need to get the ISO file from a friend?

Unless you can figure out a way to do it with a PC (which I have never tried and will let you do all the reading) then you know what you will need to get it done on a Mac. If you don't have those items then you cannot do it.
