5 picture image galley not responsive

I have 5 images in my image gallery but can’t get it to spread across 1 row on all devices. If it’s on 1 row on a desktop then on a tablet or laptop it shows 3 on 1 row then the other 2 images on a 2nd row. I tried adding columns but because I don’t have 6 images there’s a big space. So what would be the best route to get 5 images on 1 row for desktop and tablet/laptop?
