We've added error handling for invalid image URLs (like the example in the description). I also did some work to capture 404s from GoogleCloudVision, that doesn't appear to work correctly in the prod environment (example). However I won't work on that any further until we replace our GoogleCloudVision package with the official one, which Sam has already started on (T277129).

So for this ticket, I suppose all we've done is better validate the URL that was given.

OK, so as mentioned we handle invalid image urls better: e.g.

There are other types of exception (e.g.), but it looks like we will be handling those in later tickets.
