Use This: Had same problem… It worked for me…
$result = wp_get_attachment_image_src($addbooks['book-image']);
$url = $result[0];
echo '<img src="'. $url.'" >';
where,
‘$addbooks’ : name of metabox.
‘book-image’ : name of image field.
It will show image in thumbnail for showing full image. USe:
$result = wp_get_attachment_image_src($addbooks['book-image'],'full');
Hope it will help you…
Happy Coding…!!! -TK
