You'll be saving the scanned photos as .jpg. I would set up a folder in "My Pictures" specifically for these photos so they're easy to find. Once you have the pictures all scanned and saved, click on the "what's on your mind" box on your FB page. A series of icons will pop up. Click on the first one that looks like two overlapped pictures. You have options of Upload a photo, Upload an album, or Take a photo with a webcam. If you have just one pick the first option, if more than one, pick the album choice. Give it a name. You don't have to give a location. Click on "share." Click "select photos." If you want to use all the photos in the folder that you just scanned, you'll select them all, then upload. It should be pretty step by step at that point. Good luck!
