Help with diablo expansion

This doesnt have much to do about bots but i didnt know where else to go. I accidently broke my diablo II expansion cd and cannot play lod anymore. I gave up trying a while back and uninstalled d2 as well. I still have the cd key and my classic d2 disks but i need to find a way to install expansion without a cd and use my cd key on it. I was hoping someone could show me where i may be able to dl a d2 lod installer. Thanks

download an cd-img and use your cd-key

Whats a cd-img? If its not too noob of a question.

aka. Crack
I am sure you can find a copy in all common p2p servers.
