flash 5 detection

[s3ction 14]

Does anyone know the java script for detecting flash 5, and if the machine dosen't have the player the script will tell it to display an alternate jpeg

i'm using dreamweaver for this stuff..
it has some behaviors about plugin detection
but i can't help ya with the plugin detection

or maybe
try to make a little swf file (1 on1) and on the fist frame ya put the get url action, put it in the html page
that loads the page when you've got flash
otherwise put a javascript timer, that after 5 seconds, will go to the page when you haven't got the flashplugin (or change the jpeg as you want, ya can do that with the timeline in dreamweaver)
