Tile template with CMS

I’m looking a way to make/find a tile template to present several projects.
I wonder if it’s possible to merge the power of CMS collections with dynamics tiles.

Here an exemple of website : Engram – pictures of architecture

Maybe there is a way to do it using grid and a collection list, but i don’t want my pictures to resize, crop or have differents marges between them.
For now, i only managed to have a square type of things, but for some picture, i really dont like the square crop it makes.
Here the link to see my website, i would really like advices, tips, to do a tile template !
