Download Irfanview.



Once you have, open the picture and use the magnifying glasses to resize the image. Once you've found a size you're happy with, go to Image %26gt; Resize/Resample %26gt; where it says Width and Height, copy in the width and height that is shown at the top of the screen on your toolbar.How do i make a picture of someone quarter the size it already is?
