The option I chose on freevideocoding.com was "Link to Embedded Player (from image)" as you can see to prevent the player from activating when the page is opened I included an image as a cover. You can chose ANY media format to embed an MP3, I chose Windows Media format. [NOTE: the web visitor's web browser actually chooses which player will be used.]

On most pages on my food allergy site I used my software, Video Code Maker, to create the code to embed the MP3 AND "marry google ads" to the player itself. You can place any image above your player or beside it with Video Code Maker.
