You cannot move the image to a smaller partition space using W7 image software, you will need a 3rd party image software to do this.

Since you are moving to a SSD, it would be wise to install W7 clean and transfer your data using Windows Easy transfer, first run easy transfer on your older installation to back up your data, then run it again on the clean install on the new drive to import that data.

Programs will need to be reinstalled.
