How to create post gallery like in facebook?

Question

opencart

Good morning . The question is stupid and I think it has already been raised more than once, but I can not find it at all. Please advise a similar one.

The most interesting thing is that I put the same images, at least 3 of them with the same resolution of 1920 by 1080, and they lined up, cropped themselves. On it the question with masonry has disappeared at once.
Thank you very much in advance.

Answer 1

rowGrid.js

Answer 2

Just a few predefined algorithms for building a grid of pictures. The previews are actually the same size, just set to background-size: cover and adjust to the size of their cell.
