Resizing image has always been a problem in Windows OS, it lacks the support to resize image quickly. Fortunately the popular tool ImageResizer in Windows XP now has support in Windows 7 and Vista, it has native 64 bit support for 64 bit 7 and Vista.
Like it sounds, this tool lets you quickly resize a selection of multiple images at once. It’s was typically used in the past to compress photos to more manageable sizes for sharing via email (although that’s not necessary anymore since Windows Live Mail does this for you). Now, it’s more likely to be used to compress photos down for use on your web page or blog.
Simply download the installer and you will have the option to resize any image when you right click the image. You can also select multiple images and resize.
