Extract image from web page

How to extract the image from this https://www.google.com/maps/@45.8118462,15.9725486,3a,75y/data=!3m7!1e2!3m5!1sAF1QipOH6lgU7bug2ndyW-9-Uq0kgKqcKDtnGei2N5Qo!2e10!6shttps:%2F%2Flh5.googleusercontent.com%2Fp%2FAF1QipOH6lgU7bug2ndyW-9-Uq0kgKqcKDtnGei2N5Qo%3Dw150-h150-k-no-p!7i3024!8i4032

(If the link disappears let me describe how to reproduce the question. Find any shop on Google Maps that has the "shop title image" appearing in the shop details on the left side when you click on that shop. Click on that image to expand it across the whole viewport.)

I found the <canvas> element that I guess contains the image. I tried to do .getContext('2d') on that canvas element, but I keep getting null.
