In the coming weeks, we’ll be switching some internal pipelines to consolidate the internal services that manage, crop and display images used in Twitter Cards.
What is the impact?
There is no need for developers to adjust any of the code associated with the Cards images in website markup. The minimum and recommended image dimensions for summary, summary large image and player cards are not affected by this change. There is a chance that some users may notice that a few images are cropped slightly differently on being rendered in the timeline in the Twitter website or mobile apps, or in a Tweet detail view.
Feel free to contact us via the Cards forum with questions or concerns you may have regarding this update.
