Image not showing for Summary Large Card


I use the card validator to validate my url but the preview or the actual tweet is not showing my image. There is no error at all. Can someone help ? My url is :

My image size is 800 by 534 and is based on the Twitter recommendation:
Images for this Card support an aspect ratio of 2:1 with minimum dimensions of 300x157 or maximum of 4096x4096 pixels. Images must be less than 5MB in size. JPG, PNG, WEBP and GIF formats are supported.

Thank You.


The image that you’re linking to in the twitter:image tag is 150x150 pixels which is too small for a summary large image card.
