Hi, the slideshow button is always available in the default lightbox theme. You can use a custom theme to fully control the appearance of the lightbox, including adding/removing elements such as the slideshow button. See SLB’s Themes documentation for more details.
An option to disable slideshow functionality has been added to the list of things to consider for a future update.
Thanks.
Thx for the info.
I really would appreciate an update with this feature.
