You can also use an image converter. They are tools designed to do such a job, so they allow you to set much more options and fine control your results. This means better image quality and less time spent to resize the pictures.
For example a tool that may help you in the process is AZImage - see referenced links. I recommend this tool because it allows you to choose the resize algorithm under advanced options and has a trial period.
Right click on your picture. Go to: open with. Go to picture manager and click it. When picture manager opens, click on edit picture. Look on the right side and you will see resize picture. That will do it.
