My Twitter Cards have been approved for quite a while. I’ve noticed that my Photo Cards are just 240px wide (?)
The original source is way bigger (1024px) but the preview Twitter generates it’s always 240px.
I’ve looked at tweets from @mashable and they have bigger previews 480px to be exact.

I’ve tried passing a smaller original image (like Mashable) a 560px image but it still previews a 240px.
Any idea why?
Thanks in advance
