Scan the photo, put it into your photo program, then enlarge it until you can read the ribbons. If you don't have a photo program, there is a free one on Google called Picasa. If you don't want that program on your computer, just take the photo to Kinko's and have it enlarged until you can read the ribbons. No need to have it on photo paper, regular paper will work just as well. Sometimes just viewing the image in negative, black background with white writing, will make it easier to read.
Once you have identified the people by their ribbons, send the photo and the list to whichever Internet sites you think would be appropriate. Also put the url onto this rootsweb site.
