Images not coming through even though Validator Confirms them?


I’ve got an articles that the validator confirms the reference in the source is valid, however no image appears on the summary card via the validator or when I’ve tweeted the link.

The image is larger than the minimum dimension requirements and is under the file size limit.

Hello Greg,

I just took a look at the your robots.txt file at and it turns out /images/ is disallowed for all.

Twitter uses the User-Agent of Twitterbot (with version, such as Twitterbot/1.0) when crawling pages to find Twitter Cards markup. Twitter’s crawler respects robots.txt when scanning URLs, so please create an exception for your images to display in Twitter Cards.
