Load random movie button

1

hi… heres my problem . I am trying to get a single button to load different individual images with each ‘click’ , now I know a simple way to do this is by having keypoints along the timeline with which the button is directed to via ‘stop’ and ‘goto’ a.s. but what if I wanted the imge that appears to be a random choice? I presume the images would then not have to be within the timeline but called upon with a ‘load’ function? and perhaps even as .swf’s rather than jpegs? i am not sure though as i am still practicing and my flash expert mates just laugh at me struggling! all help appreciated
