Redirect gallery url

Hell o i have a problem with my galleries. I have wordpress blog where on main page are featured images. When somebody click on it, it link him to post page when he can see thumbnails of all pictures and when he click on it, it redirect him to better quality image and its ok. But when somebody click on image again it redirect him to full size image on white background. And i don’t wanna this. Is there any solution to change this link? I wanna use one link to all images from my page. is this possible?
