I use BiNG and had to deal with this problem recently when replacing a failed hard drive with a smaller one in a laptop. My solution was to restore the larger image to a hard drive with enough free space to accommodate the image (don't try to boot from it), then resize the partition small enough to fit the new smaller drive, image the now smaller partition, and restore that to the new hard drive.
Are True Image, BiNG and IforD also smart about restoring to a smaller partition?
It was some extra work, but in the case of a failed drive it was necessary. I was also lucky that I happen to have a hard drive with an unpartitioned space on it big enough the accommodate the original 60GB image. One more reason to keep the OS partition small. Personally I prefer no bigger than 20GB for the OS partition.
