404 image permalinks

Please try inserting the following code in rpr_core.php line 200

// Querying specific page (not set as home/posts page) or attachment
			if(!$query->is_home()) {
               if($query->get('page_id') !== 0 || $query->get('pagename') !== '' || $query->get('attachment_id') !== 0) {
                    return;
                }
            }

I’m sorry I can’t reproduce this faulty behaviour on my testing system. Please provide some more information on your setup, permalink structure and versions.

Still can’t reproduce the error you seem to get. Embedding images in recipes and posts works perfectly for me. Also linking those to the original file for a lightbox works.

Alright, now I understood the problem. Below you can find the function query_recipes() that solves this issue. It will be in the next release.

function query_recipes($query) {
		// Don't change query on admin page
    	if (is_admin()){
    		return;
    	}

		if ( ! is_admin() && $query->is_main_query() ) {

			// Post archive page:
    		if ( is_post_type_archive( 'rpr_recipe' ) ) {
    			//set post type to only recipes
      			$query->set('post_type', 'rpr_recipe' );
				return;
    		}

			// All other pages:
			if( !is_page() && ! is_attachment() ){
				// add post type to query
				$post_type = $query->get('post_type');
            	if( is_array( $post_type ) && ! array_key_exists( 'rpr_recipe', $post_type ) ){
            		$post_type[] = 'rpr_recipe';
            	} else {
            		$post_type = array( 'post', $post_type, 'rpr_recipe' );
            	}
            	$query->set( 'post_type', $post_type );
				return;
			}
  		}
    }
