I have a very basic test page and every parameter seems to be ok but
the image does not show up in my timeline or validator.

Card validator log doesn’t show any errors but the image just doesn’t show up.

I suspect the image file itself because when I swap it ton ogp image from another company website it shows up.
The image is a generated image by php gd library and outputted by imagepng.
I’ve done the same type of setup before and haven’t had a problem.This just happened recently.

The image shows up fine in the browser so it’s not corrupt.
If the image is the problem, please advice me what the actual problem (i.e. file size, compression…) is and what I can do specifically to solve it.

Thank you.
