I am having an issue with twitter images not appearing in onebox. This is not a general problem that I can replicate here as the same links posted to this instance display the images in the tweet. However, when I post the same link to my site, there are no images.
Any ideas what could be causing this? Other images load fine
I believe the image loading requires the Twitter API, so you’ll need to fill in twitter consumer key and twitter consumer secret in your site settings. You can leave “enable twitter logins” disabled if you like.
