View multiple images with Lightbox
Use Colorbox instead:

Formatter: Colorbox
Content image style: Hide (do not display image)
Content image style for first image: Thumbnail
Colorbox image style: None (original image)
Gallery (image grouping): Per post gallery

Under 'multiple field settings' I set it to display 'all', choosing Display type: 'Simple separator' and changing this from ', ' to ' '.
