which particular code did you use, please post the snippet here
Sure, this is the code I’m using:
add_post_type_support('topic', array('thumbnail'));
add_post_type_support('forum', array('thumbnail'));
/*
Plugin Name: bbPress - Forum Icons
Plugin URI: https://gist.github.com/ntwb/8277457

// Original Source: http://www.kristarella.com/2013/04/bbpress-forum-icons/
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
