• I am using Shortcodes Ultimate to display external domain content in a iframe using shortcode [su_lightbox src=”{External Domain URL}”][/su_lightbox].

    Iframes and Inline content render great with Ultimate ShortCodes. However, Due to the lag in loading external content there is black window that shows-up with every iframe until the content fully loads. Is it possible to display loading message or even better a loading GIF file until content gets loaded.
