The difference between this one and others is that it won't tax my server and you get your privacy. It's just an HTML and XSL file (right-click on both links and choose "Save Link/Target As" and save them to the same directory--then open images.html on your computer). When you run it for the first time, you'll get an (appropriately) scary message like "A script from "file://" is requesting enhanced abilities that are UNSAFE and could be used to compromise your machine or data." You'll have to choose 'yes,' (but only do so after you trust me ;-)
Currently, you can modify the default image height and how many images you download.
