Now adding unlimited featured images to any post/page or custom post type post is super easy. This post has multiple featured images and presented in a responsive slider by just checking a checkbox. For showing a slider with all featured images in it instead of showing the default featured image that wordpress shows we just need to check a checkbox. No shortcode required for this. This plugin replaces wordpress’s default featured image with a responsive slider filled with all featured images. Slider effects and width are manageable from backend. Set the slider’s width equal to your current featured image’s width that wordpress shows by default, when this plugin is not activated. So the slider will take the width what the featured image was taking previously.
