can anyone let me know how to add a link to a flash movie please.

A link to a html file? A link to another part of the flash swf? What...

I have a picture with text that flashes on it. I would like it to be an email link.

If your pic/text has not been converted to a button, you can either make it a
button and put this code on the button:

on (release) {
getURL("mailto:youremailaddress?subject="some subject title"");
}

or create an invisible button and place over the graphic and use the same code.
