Can I replace my pictures from my computer after creating a listing?

In Wonder Lister, when you create a listing, you specify the picture's path from your local computer. That path is permanently associated with the listing in question. If you later on replace that picture with another picture on your computer, Wonder Lister will show the new picture since it has been replaced. Thus, you unless that's your intent, you should not replace an existing picture that is in use by any listing.
Please note that the content of the picture itself is NOT saved in Wonder Lister's database, what is saved is just the path where the picture is located on your computer's hard drive.
