If you’re uploading files via your own form, a file is attached by setting post_parent of the attachment to the ID of the post you want it attached to. Setting a post thumbnail doesn’t attach the file to that post.
<?php /* if its not mobile */ if ( !wp_is_mobile() ) { /* load and show the post thumbnail */ the_post_thumbnail(); } ?> You can read on wp_is_mobile here and on the the_post_thumbnail here

It is for EXIF data. But if that’s the code you’re using, it looks like you are trying to access array elements on a function call. Try $my_data = wp_get_attachment_metadata( get_post_thumbnail_id( get_the_ID() ) ); echo $my_data[‘image_meta’][‘credit’];

If i understood you correctly, you want the featured image to be displayed or not based on whether it was uploaded or not. If so, the basic code is: <?php if( has_post_thumbnail() ) { ?> <a href=<?php the_permalink(); ?>”><img src=”https://wordpress.stackexchange.com/questions/231934/<?php the_post_thumbnail(); ?>” title=”<?php the_title(); ?>” /></a> <?php } ?> And that displays the image linking … Read more
