Windows: Google Image Search is great at showing thumbnail results, but not so hot at making full-size originals easy to download. Free and portable app Multi Image Downloader is a two-step bulk downloader that’s really simple to use.
Multi Image Downloader can’t do its own searching, but instead asks you to copy and paste the URL address from any Google Image Search. Given that Google now lets searchers pin down exact sizes and color tendencies, it makes some sense that this tiny app wouldn’t bother to re-create its own search interface.
Multi Image Downloader is a free download for Windows systems only, and works great from a portable USB drive.
