My engine mounts are as flat as can be but don't cause a vibration...
Does the engine run fine when it vibrates, or does it seem to struggle or misfire? Have you checked for bad wheel bearings or loose lug bolts? Is a suspension piece in the front (like the lower A-Arm) cracked?
EDIT: Oh, and I use my scanner as I don't yet have a digital cam (though that should change soon...). It works fine, really. If you can, just set the quality to 150 dpi (any higher will just make it huge) and save as a jpeg with 25-50% compression. If that makes any sense... but it should if you know what master/slave means
