I will vote for this feature as well!
This has p*ssed me off sooo many times I have almost changed to another product.
Being able to restore an image to a smaller partition/drive is something I need almost every day.
Even changing between hard drives from the same manufacturer, of the same size but different versions can be a no go because of this restriction with ShadowProtect. e.g. I had a PC with a 40GB Seagate 7200.5 that had bad sectors - Made an image and replaced hard drive with a 40GB Seagate 7200.6 but because the 7200.6 was slightly smaller (Even though Seagate calls them both 40GB) I could not restore the image!
