URL Downloader downloads all images in a series for the image you tell 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 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.
It's as easy as 1 2 3: Give the path for one of the images, push the GO!, grab the all the images.
Just remember the obvious requirements: Photos in a series, logically numbered, and not behind login or other security (this app does not even attempt to support logins, keys, download of protected content, etc).
This Mac App optionally supports the Touch Bar available on some 2016 and newer devices.
