The newly resized images are created alongside the originals. The user only has to right-click on one or more image files in Windows Explorer, choose the option, and quickly resize the selected image(s) without opening an image editor (as pictured above). It quickly grew in popularity as it added a simple 'Resize Pictures' option to the Windows explorer context menu.

The original free ImageResizer (520KB) tool, which only worked for the 32-bit version of Windows XP, is still available from Microsoft.

The clone was created by Brice Lambson, a professional software developer currently employed by ACS. The tool is available in both 32-bit (2.06MB) and 64-bit (1.56MB). The Image Resizer Powertoy Clone for Windows is available for free on CodePlex, an open source project hosting website created by Microsoft, meaning the source code is available for anyone to see. One of the most popular Windows XP PowerToys has been rewritten so that it can work with Windows Vista and Windows 7, in 32-bit as well as 64-bit.
