Why are the images in my summary cards getting cropped to rectangles when they are squares?


#1

In the card validator it shows the images as being square, but in actual posts, they are rectangles. The source images are squares.

Oops, I deleted that tweet by accident because I thought it was a random testing tweet, an example is here https://twitter.com/lizperley/status/491647822022717440

Hi, Getting the same for some test tweets https://twitter.com/IWtesting123/status/490165497049407490 is an example. As @lizperley the validator is showing the image in its correct aspect ratio. The image itself is 120x120 pixels. The page url is http://www.water.ie/about-us/jobs/commercial-support-office/
