Image resizer tools are one of the most frequently used by me. Most image processing software has this feature, such as ACD See or Adobe Photoshop. But with those tools you have to open the application and then resize the images.
To simplify the idea, Powertoys comes with simple steps to resize the image. Just one right-click, fill in the size you need, and your image is resized. Very simple, light, and doesn’t need a big software package to do that. But unfortunately Powertoys only works for Windows XP. Powertoys stopped its support for Windows Vista and Windows 7.
After digging around for a while, I finally found a Powertoys clone that supports Windows Vista and Windows 7! It is on CodePlex developed by BriceLambson. What it does is just the same as Powertoys from Windows XP. It allows you to right-click on one or more image files in Windows Explorer to resize them. Plus it is extended to support 32-bit and 64-bit versions of Windows 2000, Vista, and Windows 7.
