Envira Gallery Slideshow Addon GPL Overview:

• Do you want to create a slideshow for your WordPress galleries?
• You see most WordPress gallery slideshow plugins are bloated and will slow down your site. Half the time they don’t even work properly.
• We saw this problem and fixed it by releasing a slideshow addon for Envira Gallery.
• The slideshow addon enables you to create slideshows from your galleries.
• Once enabled, you can choose to either enable/disable the slideshow setting on a per-gallery basis, and you can also adjust the autoplay and speed settings.
• After the slideshow is enabled on your WordPress gallery, the toolbar will display pause/play UI elements for the slideshow. Assuming you have keyboard navigation enabled, you can also use the space bar to control the slideshow.
• The slideshow works once the lightbox has been opened. You can set it so it starts automatically or when the user manually clicks to start the slideshow.
• We have created a demo gallery that utilizes our slideshow addon. Autoplay is not enabled on this slideshow, so you must click the Play button for the slideshow to begin.
