If you often use Youtube videos in your blog posts, you would have always wanted to display a thumbnail from the video on the archive or homepage for your readers. Today I will tell you how to do that using a WordPress shortcode.
You will need to copy the following code in your theme’s “functions.php”. Thesis Theme users should copy this code to “custom_functions.php”.
[php]
/*
Shortcode to display youtube thumbnail on your wordpress blog.
Usage:
[youtube_thumb id="VIDEO_ID" img="0" align="left"]
VIDEO_ID= Youtube video id
img=0,1,2 or 3
align= left,right,center
*/
function wp_youtube_video_thumbnail($atts) {
extract(shortcode_atts(array(
‘id’ => ”,
‘img’ => ’0′,
‘align’=>’left’
), $atts));
$align_class=’align’.$align;
return ‘</pre>
<img id="" src="<a href=" alt="" />
<pre>http://img.youtube.com/vi/’.$id.’/’.$img.’.jpg" alt="" class="’.$align_class.’" />’;
}
add_shortcode(‘youtube_thumb’, ‘wp_youtube_video_thumbnail’);
[/php]
Once done, you can use the shortcode. It accept 3 parameters: video ID, image size, and alignment. This shortcode uses Youtube API to create a thumbnail from the video.
