How can I make more interesting layouts? My grid tends to arrange itself into columns.

To get more interesting layouts you basically need to play a bit with image sizes and settings. Follow these tips:

  1. use images with different sizes;
  2. play a bit with the Image size factor and Grid size parameters;
  3. change the order of an image and see the final result.

Sometimes a small change can lead to a completely new layout.
