It’s somehow too high; if you place it at 0,0 or don’t specify other coordinates, it’ll sit at the bottom. It’s not at the bottom, the ankles are visible. 
It’ll depend on what image editing program you use.
I personally use Paint for short jobs like this:
- Copy image, paste into Paint
- Ensure that dimensions are right (height will be 1136px)
- Zoom out so that you can see the blue-grey background behind the canvas
- Click on background to de-select the image
- Drag right side of canvas to make image less wide
But other image editing programs work just as well.
