Once you have saved the pictures on your computer, you can go to Zillow, or gsbor.com and use the photo tab and select upload.
The more pictures the better. Most important are front of home, kitchen, living room, master bedroom, other living areas and back yard.
Let me know if I can help you with the sell of your home.
