I've created a button that is linked to a picture I have in the same folder that my movie is saved in...my movie is called site and the picture is before1.jpg.
My code is like this for the button.

on (release) {
getURL("before1.jpg");
}

I don't specify a location since it's in the same directory...It just comes up a white page and i've tried to search google for an answer but no luck.
