upload and replace selected image using php

I have a form that will be used to edit various fields including images. Everything works on this form except the images. When I choose the image i want to replace and upload the new image the location of the others get erased on the MySQL database and I'm just left with the one I replaced. How can I just change the image I pick to replace without erasing the location of the others? Is there a way just to tell the script to only replace the image that corresponds with the image selected? Thank You
