Horizontal Photo Grid with varying height


I am creating a portfolio website for my photo and video work. I am trying to create a mosaic photo grid, that shows the images in their full original aspect ratio, without cropping them. I want the photo’s to fill the entire row horizontally and let the height adjust automatically to facilitate that, like on this site: Lifeshots Photography - PRODUCT I am not looking for a masonry grid.

The only way I have found is to adjust width of each column for every row, but is there a way to do this automatically?
