It doesn't really work that way.
Say your HDD failed and you had an image on your external HDD. What you would do is.
1) Replace the HDD
2) You may need format the new HDD depending on the imaging software.
3) For a Macrium image you would boot from the Macrium rescue DVD. You can use a USB flash drive but you need to make one. Restore the image to the new HDD.
4) For a Windows image you boot from a System Repair DVD which windows can make for you or get from elsewhere if necessary. If you want to boot from a USB flash drive you will need to make one. Restore the image to the new HDD.
5) You may then need to run the System repair disk/usb a few times to fix up loose ends.
No matter what imaging program you use you always need to have a Windows system repair DVD/USB. For this and other repair jobs. Don't wait until you get into trouble.
This may appear complicated but I'm afraid this is the process. You can see having a DVD drive can be handy. It's also handy when software comes on DVDs.
