In order to accomplish what your thinking you will need some type of OCR (optical character recognition) software. What you have now is nothing more than an image with nothing that the program (word) can decide what is available for selecting. Some scanners come with some sort of OCR on the disc provided with the equipment. You would want to install that and then scan it again using that software.
Another choice is just putting the scanned images on a site like photobucket and then posting a link to those images.
