Image preview blacklist
Image Preview: Add a site blacklist to prevent image previews from selected sites.
Example: Someone can set up private repositories on github that aren't visible to users that aren't logged in and aren't members of the organization. Link preview currently creates a preview of the root github page. This is pretty annoying when you're sharing links to pull requests with coworkers.

came here to post the same idea, for the very same problem.
its really annoying to have the chat cluttert with the very generic "default preview" one gets for github private repo/issue links.
on the other hand, having the preview for public issues is really helpful.
at best mattermost could figure out whether the preview beeing rendered is the githubs default preview or a more usefull one
