MDA tried to put in code that prevented malformed image tags. Since bbPress uses raw html and not bbcode by default, it’s always something to consider. However you can run a minimal plugin to allow any and all images quite easily:

add_filter( 'bb_allowed_tags', 'allow_images_allowed_tags' );

function allow_images_allowed_tags( $tags ) {$tags['img'] = array('src' => array(), 'title' => array(), 'alt' => array()); return $tags; }

That’s all that’s needed to permit the image tag.
