Height image in column gutenberg

Hi
I use gutenberg for the layout of my pages and I have a problem.
In one page, I have created four columns. In the first three, I want to add images. The first two images are in portrait format and the third is in landscape. I would like the height of these three images to be the same so that they are well aligned. Because at the moment, I have my first two images well aligned, but the third is not as high.
What is the best way to achieve this? I would like to point out that I am developing my own theme, so it is not a problem for me to work on the code to optimise this as best as possible.

Thanks for help
