You mean as in new images being added? Well that's fine, other contributors will be adding images too. If you want your image to be the top image you can just put it on-top and move the previous one to the gallery with the "This page" option before removing it for your image. Generally that is how galleries work. If you feel an image is sub-par you just move it a little lower down so the other contributor's image is still on the page but not the headline image.
