More newb script questions

I am making a portfolio for my website and here is the beginning of my script.

stop();

//setting up the list of frame names for the buttons
imagelist = [“horror”,“legs”,“chair”];

//‘next’ button setup
next_b.onRelease = function() {
gotoAndPlay (imagelist[0]);
}


Now i want the button to cycle through the arrays so that everytime you hit the button it goes to the next frame instance that i’ve named. In this case imagelist[0] is horror so next time you hit button i want it to goto imagelist[1] or ‘legs.’ Also I need to set a stop action for this (im guessing loop) so that it stops at the array length.

Thanks for your time & help!
