Hawkeye is correct, you will need either a Win-7 DVD installation disk, or a Recovery CD made before or during the Image backup process, to restore the Image over to your new HDD. I am not certain, but probably you could use any Win-7 DVD installation disk to boot into the Win-RE (recovery environment). When you reach the Windows Install Screen put in Date/Time, Language, Keyboard, and on the next screen, choose Repair Your Computer, then System Recovery Options. Then choose System Image Recovery. With your removable WD HDD connected, it will search for your Image BackUp and should find it, or point to it. You will need to choose to restore the image to a different drive (your new HDD), which is different from the original HDD. Hopefully that will restore all partitions from the Image file back on your new HDD and get you going again. There shouldn't be a problem from the licensing standpoint, since your restored Image will be on the original computer and motherboard that it was licensed to by Dell.
