Make smaller versions of your images, even using right click, with Easy Thumbnails
Easy Thumbnails is a free utility for creating thumbnail images and scaled-down/up copies from a wide range of picture formats. You can use slider controls to rotate images and adjust their contrast, brightness, sharpness and quality, and check out the results with the built-in viewer.
Thumbnails can be created in any existing folder or a new folder, and you can identify them by adding a prefix or suffix to their filename. If you’re an image-processing enthusiast, you’ll enjoy having a choice of eleven resampling filters for the best possible results.
You can convert small batches of images inside Windows Explorer from the File menu or with a right-click of the mouse, display thumbnails in your browser, and even take advantage of command-line switches to generate thumbnails seamlessly from other programs.
You can also save your thumbnails to a Web page using a HTML template that you can easily customize to create your own layouts.
