I need some help to develop these two galleries, due to a lack of knowledge to scripting! ;(

i would like to have a slide show to have an auto run and forward and back buttons, but the code in thes tuts is a bit over my head!

I do have this simpler code with fwd and bck buttons that works, just need to use a set interval to get a slideshow going on, PS it doesn’t have to be XML.

//my simple code
maxImages = 4;
toLoad = 1;

imagenav.btnFwd.onPress = function() {
imageForward();
};

imagenav.btnBack.onPress = function() {
imageBack();
};

//------------------------------

imageForward = function () {

toLoad++;
if (toLoad>maxImages) {
	toLoad = 1;
}
if (toLoad<1) {
	toLoad = maxImages;
} 

holder.loadMovie("images/image_0"+toLoad+".jpg");

};

imageBack = function () {
toLoad–;
if (toLoad<1) {
toLoad = maxImages;
}
if (toLoad>maxImages) {
toLoad = 1;
}

holder.loadMovie("images/image_0"+toLoad+".jpg");

};

any ideas gratefully received
