How can I minimize a picture to put into a scroll box without dowloading anything or buying anything?

You need to edit the picture in any picture editing software. Even Paint can do this through the Stretch/Skew option. This comes with Windows. This is a simple function that any photo editing software can do that is already loaded on your computer. No need to download or buy anything.
