Vertical masonry doesn't work well to communicate an ordered list of items. Photos are often just that...a story of an experience that happened chronologically.

The inability to read left to right on columnar data makes this really hard.

If something really happened chronologically, then perhaps it's acceptable to have a horizontal scrollbar, or not right-justify the right edge.

This particular algorithm seems to mix up the order of the photos in order to best fit them on a line, so it can hardly be said to show chronological order.
