I plan to add 100+ images in my slideshow. Does WOWSlider allow it? Should all images be pre-loaded before slideshow will start the playing?

WOWSlider makes it easy to have a slideshow with hundreds of images.

To ensure the slideshow loads quickly and works seamlessly in any environment, you should use the ‘on-demand image loading’ option.

In order to turn this on, go to the ‘Properties’ window by clicking on the spanner/screwdriver icon in the navigation bar at the top of the screen. (You can also access the properties window by going to Slider —> Properties in the menu bar).

In the new window that opens, look down the options in the left column, until you see ‘On-demand image loading’. Check this box.

You can now add as many images to your slideshow as you need.

You can see an example of a slideshow with 100+ images at and that uses ‘on-demand image loading’ at: http://wowslider.com/jquery-slideshow-huge-demo.html
