Show Full Background Image

I am trying to reposition the background image so that it shows a different portion of the picture.  How would I do this?  It seems like jotForm is enlarging the image when I upload it causing portions of the picture not to show.

In the Form Designer view, I the image does not fully show but if you open the form in preview mode, you will see that the image fits with the height of your form and the width of the screen. Please see below GIF which shows the image fully shown as the background of your form.
