Noterai che, dalle ultime versioni, Adobe (formerly Macromedia) Flash crea automaticamente nell' <head> questo script nell'html della pagina quando la si pubblica

ti ho messo in grassetto le parti che devi/puoi modificare, inserendo il tuo html [comprese quindi immagini]...del tipo "non hai il flash player, scaricalo adesso..."+ il logo del sito ecc. ecc.
quindi ti puoi [quasi] rilassare 
p.s. per fare le prove ti consiglio di disinstallare il Flash Player:
