This free application from Microsoft has some great uses. Basically it does exactly what the name implies, it adds the ability to resize images. But this one is accessible from a right-click on any image.
It is a limited use application, in that it offers only four preset image sizes. If you click the ‘Advanced’ button it also offers the ability to set a custom size. Another nice feature is you can select multiple image files and convert all to a new size as a batch process.
