Justified/Masonry layout is not working

If you have set your galleries or images to display in the Justified layout mode and are not seeing anything changing, there is a likely cause: all your thumbnails are the same size/orientation and so you can't see the effect. The masonry effect can only be seen when you have different sized/oriented images. Things to check:

• Do you have the thumbnail setting set to crop? If so, uncheck this setting. You will have to regenerate all your thumbnails.
• Is every image in the gallery a horizontal image? Or every image a vertical image? If so, nothing the masonry add-on can do - you would have to look at a gallery with different sized thumbnail images.
