text: when you are setting up your listing, after you have done the description, scroll down, there is an option to add photos.  You simply click the browse button, and it will let you search your computer for the photo.  then you just continue the listing.  The only problem is if your photos are to large.  Also, if you have pop-up blocker, you may want to hold the control key down while the photo is loading...it seems to help
