I’m trying to make a twiter card to work with an summary_large_image type but unfortunatly, image is not showing.
I have checked the robots.txt, and the png (with pngcheck) but I can’t make it to work.
Can you please help me ?
Here’s the url: http://citytrail.salomonrunning.com/fr/share-run/1124
Here’s the image: http://citytrail.salomonrunning.com/map/run-1124.png
The image is generated from a PHP script with imagepng() function.
Thank you a lot for your help!
