Sorry for being thick!
Your link seems to suggest the googelcontent is translating a .jpg into a .webp:
Code:

Sticking the image URL only (from your code) in to both FF and IE11 results in:
Do you want to open or save Christmas2016_26Dec16.webp
AIUI, Mozilla doesn't natively support webp, neither (it seems do IE and Safari), so the browser cannot deal with it, and when embedded in HTML as in the original post, it simply doesn't appear.
So the problem seems to be a proprietary image standard that google are using, that no-one else supports.
It looks like you would have to download the "image" and then use a 3rd-party converter to view it.
