How is that better? It's still a grid of images that seem to be constrained to a more or less rectangular grid. I'm thinking more of a dynamic grid where there is a mix of sizes of horizontal and vertical images.
The point being raised is that dynamic image grids don't actually make for a good UX. They might look more visually interesting at a superficial glance, but when you're actually using the interface to browse images, predictability wins out. Even having mixed-orientation images, where there is some degree of extra whitespace between images, does not change this. It is way easier to digest the content when your eyes can reliably scan one line at a time without having to bounce around everywhere to track the flow of the dynamic grid.
