Ah, that’s the problem then.
When you select the Image URL option in ACF, ACF stores in the database the attachment ID of the image instead of the image URL. That’s why WPP doesn’t display your image: the value coming from your custom field isn’t an image URL, it’s an integer number.
To have WPP use the images you set via ACF:
1. Go to Plugins > Plugin Editor and select WordPress Popular Posts.
2. Click on src/Image.php to edit this file.
3. Find this block of code (around line 186) and replace it with this:
if ( ! $thumb_url || ! $this->is_image_url($thumb_url) ) {
// Is this an attachment ID instead of an image URL?
$thumb_url = $thumb_url && Helper::is_number($thumb_url) ? wp_get_attachment_image_src($thumb_url, 'full') : null;
$thumb_url = is_array($thumb_url) ? $thumb_url[0] : null;
}
if ( $thumb_url ) {
/**
* Filters CSS classes assigned to the thumbnail
*
* @since 5.0.0
* @param string Original ALT attribute
* @param int The post ID
* @return string The new ALT attribute
*/
$alt = apply_filters(
'wpp_thumbnail_alt_attribute',
'',
$post_object->id
);
}
4. Next, find this block of code (around line 259) and replace that with this:
if ( ! $thumb_url || ! $this->is_image_url($thumb_url) ) {
// Is this an attachment ID instead of an image URL?
// If so, try to fetch the image
$thumb_url = $thumb_url && Helper::is_number($thumb_url) ? wp_get_attachment_image_src($thumb_url, 'full') : null;
$thumb_url = is_array($thumb_url) ? $thumb_url[0] : null;
}
if ( $thumb_url && $this->is_image_url($thumb_url) ) {
$file_path = $this->url_to_path($thumb_url, $post_object->id);
}
5. Click on the Update File button to save changes.
That should do the trick.
