How do I put a shortcut to a picture on the home screen of my LG20

[CMG3]

I have a picture of the 5 steps to follow if I'm in a vehicle accident and I want that available QUICKLY in case I'm in and ACCIDENT. So I thought I'd put a link to the picture I took of that .pdf file so I could get to it NOW!!! Thanks:

Welcome to Android Central! Try installing Total Commander, which is free and ad-free. It'll give you a widget that can act as a shortcut to a specific file. If you choose that image file, tapping the shortcut widget will open the image.
