Example of a combination of the Jusitfied-Gallery plugin (Row height: 120, Margins: 4, Border 20, Last row: center, Background: transparent.) and the Slide Show 4Lightbox. The Image bounds settings are Images: 1920x1080, Thumbnails: 500x140 and responsive Theme image with display width 96%. The theme image, which is fetched from the jAbum v15 folder panel, is displayed as a responsive picture with display width 96%; it is disabled for display in the thumbnails table and as slide page.
The scrollbars are hidden, so use the scroll-wheel on a PC for vertical scrolling
