shows content only if the attached file of current posting is an MP3
Works only within the lb:loop_postings. This is especially useful for hiding the flash player if there’s no mp3-content to be played. Note that Flash can only play mp3, while other Loudblog-elements can handle all kinds of audio data, such as AAC, WMA or OGG.
Usage
