From the developer:
This app downloads all images in a series for the image you ask it to download. For example, if you search for "Bjork" in Google or Bing Images and discover Bjork-12.jpg on a site, there is likely a Bjork-1.jpg, Bjork-2.jpg, and so on. This app automatically downloads them all for you. And it is designed to work around naming challenges that might exit.
