If all software is loaded on the computer and I would think it has been when you installed the CD that came with it.. Look at the printer this is a 3 in 1 unit... There should be a Scan Button along with all the other buttons on the Printer itself.. Put picture under the flat bed scanner cover, close cover, and Push the Scan Button~! The pic then should pop up on the screen when it is being scanned...Once scanned save to a File...Then up load that picture unto whatever picture storage site you use..
I always make a Separate Picture file (A NEW Folder) and Name it Scanned Pictures... That way I know where that picture or pictures are~!! When I want to load them up on the net...
