Invert Order

First, congratulations on the plugin. Very efficient and functional. I just finished creating a slideshow of about a hundred images with name and description, when I realized that I inserted them in the wrong order. Is there a way to have the slideshow play in reverse order or to reverse the order of the images in the slide options without dragging every single pic up and down?

Thanks ??
