Icon over thumbnail according to post format
You can use get_post_format($post_id) to retrieve each post’s format, then you can assign a class to each post based on it’s format.

a tricky question about featured image
After add_post_meta($post_id, ‘_standard_image’, trailingslashit($uploaddir[‘url’]) . $filename); paste set_post_thumbnail($post_id, $attach_id); What this is doing is taking the attachment that is created in this function and adding it as a featured image. Hope that helps.

A little confusing, perhaps, altogether. I know … Read more
Facebook Does Not Grab Correct og:Image

Can I prevent get_the_post_thumbnail from falling back to the global post ID?
As you are storing posts IDs in meta fields of another post (let’s call this post “the main post”), you can get that meta field and if it is empty, just avoid the use of get_the_post_thumbnail(). (For the next examples, I suppose that you are stroing one post ID in one meta field of the … Read more
