Why don't you use any form of compression on your image? If I were to download this using the internet access I have at home, it'd take me 2 months (I only have my cell phone at home, and it has a bandwidth cap). I downloaded it from my parent's, but I still required compressing the image (to split it to fat32 be fat32 compatible). I ran out of time (I had to get to work), but 7zip compressed the first 9 GB to 4 GB. That's a huge savings in time, space, and bandwidth. If that compression ratio holds true, your 18+ GB image file should reduce down to 7 GB. That's still huge, but it's small enough that I could actually download it from home. Please, have some sense and compress your image! Not everyone has the ability to download such massive files without consequences.
