Think back to the last time you read an article on your mobile device and how small the images were displayed. If those images contained important details relevant to the article, the information may be overlooked leaving the article to appear incomplete. By utilizing a lightbox image gallery, the author of the article can still share a small version of the image that allows the reader to choose if they wish to see a larger version by clicking on it. This really becomes important for articles that include multiple images to avoid slow loading speeds due to the bloated images sizes.
Grouping Images with Purpose:
Lightbox galleries also allow the author to select which images should be combined together in a single gallery. If your article has multiple sections, using different groups of images will help the reader better understand the separation of ideas being presented. By clicking the image to the right, you will notice the lightbox contains a gallery of images that have been selected to be displayed together.
