+ * the sprite is 200 px tall, it's divided into four sections 50px each).

+ * fourth section is "disabled". 
+ * If the parameter is not supplied, the uploader is rendered transparent,
+ * and it's the developer's responsibility to create a visible UI below it.
+ * @param forceTransparent {Boolean} This parameter, if true, forces the Flash
+ * UI to be rendered with wmode set to "transparent". This behavior is useful 
+ * in conjunction with non-rectangular button skins with PNG transparency.
