Often we end up having big images that needs to resized because we have to mail, upload, make them smaller to save hard disk space. Lets just say we really do not need a something so big. What do we do then? *sign* can I have something very simple one step process to do to achieve this?

We have lots of images editing tools available but those are not necessary because they are softwares that are big, some are trial version, for some we may have to pay. Its not worth taking so much pain for
