even size for photos

hi
as you can see here https://www.stickit2wall.co.il/product-category/%d7%9e%d7%93%d7%91%d7%a7%d7%95%d7%aa-%d7%9c%d7%97%d7%93%d7%a8%d7%99-%d7%aa%d7%99%d7%a0%d7%95%d7%a7%d7%95%d7%aa/ the sizes are diffrent for the photos. is there a way to set even size space so all the photos will be displaid in an even size? i dont want to go one by one and edit but a one click solution.
thanks
