Hi Robert, thanks for your reply!
Writing a plugin was the first thing I did, and that worked fantastically—no matter if I put it in lib/onebox/engine, or as a separate plugin. The caveat is that we are on a hosted plan, where plugins are understandably not allowed on multi-tenant plans, leaving cooking in Rails out of the question.
That leaves us with one of three opportunities:
- Running our own instance
- Hacking something on the client-side, if it might work
- Submit a PR to mainline Discourse
To frame a question here. I’m not sure if such a contribution would be accepted, especially if it loads an image just to hide it. How might I find out?
