using nero go to create a new vcd and drag and drop your photo jpeg files into the add files window, change the pause setting next to every pic from infinate (you have to press next for each pic otherwise) to about 3 secs. once you finished click burn. if your using nero express dont put a vcd menu on the disc as you can only view 99 pics. nero converts all the jpegs into a single dat file and its done. check your dvd plays vcds first though. copy your new disc a few times and save a fortune on reprints for the family.
hope it helps
