Slack bot keeps asking to link my Google Drive account. I couldn’t find that file in Google Drive. Do I have the correct Google Drive account information for you here?
But I do not want to ever link my Google Drive account. How can I disable this functionality with my Slack bot?
Select the bot which you want to remove
Select revoke permissions and authorizations to this app
Select Remove the bot
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.

You're probably aware that you can disable or remove the app by visiting https://[YOUR_TEAM_NAME].slack.com/apps (search for app, will give option to disable/remove top right). But this applies to the entire team which may not be your intention.
Maybe you can create a throw-away google account you don't use for anything else just so it stops asking you?
