Philippe Daouadi	15ffc4143c	Fix preview of imgur and Tenor URLs. (#11669) ... By scraping Open Graph information from the HTML even when an autodiscovery endpoint is found. The results are then combined to capture as much information as possible from the page.	2022-01-18 13:20:24 -05:00
Patrick Cloke	ba7a91aea5	Refactor oEmbed previews (#10814) ... The major change is moving the decision of whether to use oEmbed further up the call-stack. This reverts the _download_url method to being a "dumb" functionwhich takes a single URL and downloads it (as it was before #7920). This also makes more minor refactorings: * Renames internal variables for clarity. * Factors out shared code between the HTML and rich oEmbed previews. * Fixes tests to preview an oEmbed image.	2021-09-21 16:09:57 +00:00
