Ok so heres the code i've used
<embed
src="player.swf"
width="250"
height="20"
bgcolor="undefined"
allowscriptaccess="always"
<strong>allowfullscreen="false"</strong>
flashvars="&file=mysong.mp3"
/>For some reason it still shows the fullscreen button though, all my false has done is make it none clickable. But its still there! lol
How do i remove that button so it doesnt show up any more?

<embedsrc="player.swf"
width="250"
height="20"
bgcolor="undefined"
allowscriptaccess="always"
allowfullscreen="false"
flashvars="file=mysong.mp3<strong>&fullscreen=false</strong>"
/>
allowfullscreen is a parameter for the Adobe Flash Player.
fullscreen is a flashvar for the JW FLV Media Player.
Both are required to prevent the fullscreen mode from working, but you can get away with just fullscreen=false if all you want to do is get rid of the button.
