I made my page and watched video on how to share a chosen page on social media. I did everything adviced but the post photo does not tag along and in some there is only the text link. What did I do wrong?
In your OP a year ago you mention “post photo” which implies that you’re trying to setup a blog collection page for social media sharing. However I don’t see an image field in your Blog Post collection.
Since your readonly actually is to your Projects template page I’ll use that one as the example.
For the image, you have to assign the image field you want to use for your Open Graph data.
Note the image has to be the right dimensions, aspect ratio, and file type for the social media you’re wanting to support. I’d avoid AVIF’s here, and 2:1 like 1600:800 is probably good for most services. I haven’t reviewed the specs in awhile.
