Image Resizer Powertoy Clone for Windows is a free shell extension for Windows XP and Vista, that allows you to resize images directly from Explorer via the context menu. Why bother opening an image editor?
The tool is a “clone” of the original Image Resizer Powertoy from Microsoft which worked for 32-bit Windows XP. The clone extends the support to Windows Vista as well as Windows XP in both 32 and 64-bit editions.
By default, the tool provides you with 4 different sizes to select, from small (640 by 480 pixels) to large (1,024 by 768 pixels) and even handheld devices sized image (240 by 320 pixels). The advanced option allows you to set custom sizes for the images. It’s pretty nifty.
