That is the link to the Google Drive image viewer, rather than a link to the image itself. If you check the URL for the image when you visit that link, you get an URL like:
blob:https%3A//drive.google.com/32efcf38-d7e6-4656-9046-eede4c4880f9
That's not useful. You need to do a little URL manipulation of your original URL to be able to hotlink it. You need to take your original URL, which looks like this:
https://drive.google.com/file/d/{file-id}/view?usp=sharing
And change it to this:
https://drive.google.com/uc?export=view&id={file-id}
So, in your specific case:
https://drive.google.com/uc?export=view&id=0B-NH9wCC0oM4U2x2WTZ3ZkJ1a1k
And now you should be able to see your image:
Of course, the "sharing" setting for the image must be set to "public on the web". (Which you've already done.)
This URL manipulation is completely undocumented in the Google Support documentation. As such, you are duly warned that this method may stop working. You might want to find a more stable image storage solution. Imgur is purpose-built for this sort of thing, but there are plenty of other alternatives.
Credit where credit is due: I found this solution on the Google Operating System blog, which in turn found it at this question on Stack Overflow: Displaying files (e.g. images) stored in Google Drive on a website.
