Wordpress - How to get a gif working as a Featured Image? Big Problem?!

[DanielBlue]

Since some time I am trying to get a gif working as a featured image on wordpress. I know it can be done but all modification I made till now did not work! They are working inside the post but not on the frontpage… any ideas?

You can add this code to functions.php in your theme folder

<?php $thumb_url = get_the_post_thumbnail_url();
	  $thumb_low = strtolower($thumb_url);
	  if (strpos($thumb_low, '.gif') === false) {
	  	$thumb_size = 'large';
	  } else {
	  	$thumb_size = 'full';
	  } ?>

Normally, Wordpress will process your featured images via this function the_post_thumbnail() and it will resize your image to 150x150 thus your gif image will not work. Now when you added that function then it will always display your image size as uploaded.

Hope that helped.

Thank you but when adding the code the page is not working anymore at all.

Make sure that you only add

$thumb_url = get_the_post_thumbnail_url();
	  $thumb_low = strtolower($thumb_url);
	  if (strpos($thumb_low, '.gif') === false) {
	  	$thumb_size = 'large';
	  } else {
	  	$thumb_size = 'full';
	  }

Remove open/close PHP tag in codes above.

<?php

?>

No, not working. I am using a premium theme, looks like it's not made for doing so.

It is not more differences between Wordpress default themes, free and premium themes out there.

You might need someone look into codes in your theme to fix this issue.
