If at all possible it would be far easier to ask your friend to send the picture again as one single image (preferably as a proper image file, not a word doc)
If the scan is too large to be sent as one email (I suspect this is why they done it in 5 separate mails to start with) then suggest they use a file hosting site such as yousendit or similar, then they can upload the pic there and simply send you the link to download the pic in it's entirety.
