Display5 offers a content library that can be used to create slides and re-use images in other panels and shows. To add images to the content library we offer a batch upload tool that can be used to mass upload to the Show. This widget is simple to use. Click on the browse button to open a file dialog which allows you to select multiple files at once.
The destination panel is indicated for you, but you are free to use the images in any panel or show once they are loaded.
