Randomness hopelessness

TonyGrgurevic · October 19, 2006, 7:24am

I have a AS2 slideshow that plays through a few dynamic (XML) images, but I would like to randomize which image is being displayed…

I have searched the forums looking for how to do this but I cant get anything workin…

Any help is appreciated

cheers,
