Photo gallery question about fade in/out

i tried searching this already but couldn’t find anything too useful… So hope u guys can help me with this…

I have a working photo gallery that follows this tutorial http://www.kirupa.com/developer/mx/photogallery.htm … but then i want to modify it so that when one presses the left arrow key, the next pic fades in before the current pic finish fading out… sth like #4 under javascript in [url=“http://podlob.com/”]http://podlob.com/ … Hope this is not too difficult to do…

thanks alot
