Hi, I’m using this code from @stagger-lee to enable ability to create featured images in topics:

Add Featured Image to New Topics in Frontend WYSWYG

When ever I create featured image, they all come out to 400px by 400px. Is there a way to set the featured images to a different size, such as 600px by 400px?

Thank you for any suggestions.

Sure, this is the code I’m using:

add_post_type_support('topic', array('thumbnail'));
add_post_type_support('forum', array('thumbnail'));

function ks_forum_icons() {
	if ( 'topic' == get_post_type() ) {
		global $post;
	    if ( has_post_thumbnail($post->ID) )
	    	echo get_the_post_thumbnail($post->ID,'thumbnail',array('class' => 'alignleft forum-icon'));
	 }
}
add_action('bbp_theme_before_topic_title','ks_forum_icons');

without further digging, the function

echo get_the_post_thumbnail

seems to support

thumbnail
medium
large
full

so you can have for instance

echo get_the_post_thumbnail($post->ID,'medium',array('class' => 'alignleft forum-icon'));
echo get_the_post_thumbnail($post->ID,'large',array('class' => 'alignleft forum-icon'));

you can also play with these settings – see
