Hello,

I have this XML based slide show for Flash that works fairly well
(based on the XML slideshow tutorial on the site). The slide show
currently preloads the images between the slides. It works pretty well
on a broadband connection since the load time doesn't seem to get in
the way of viewing the pictures. However, it gets pretty annoying to
see the loading screen between each image. I was wondering can I tell
flash to preload all the images on the first slide before starting the
slide show? An example of the code in action is at
http://andygoldman.com/busanutenterp...slideshow.html .

Here is the actionscript that currently drives the slide show:

("picture" is the name of the movie clip that the images load into)

function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
name = [];
dimensions = [];
addinfo = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image[i] = xmlNode.childNodes[i].childNodes[0].firstChild.nodeValue;
name[i] = xmlNode.childNodes[i].childNodes[1].firstChild.nodeValue;
dimensions[i] = xmlNode.childNodes[i].childNodes[2].firstChild.nodeValue;
addinfo[i] = xmlNode.childNodes[i].childNodes[3].firstChild.nodeValue;
}
firstImage();
} else {
content = "file not loaded!";
}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
/////////////////////////////////////
listen = new Object();
listen.onKeyDown = function() {
if (Key.getCode() == Key.LEFT) {
prevImage();
} else if (Key.getCode() == Key.RIGHT) {
nextImage();
}
};
Key.addListener(listen);
previous_btn.onRelease = function() {
prevImage();
};
next_btn.onRelease = function() {
nextImage();
};
/////////////////////////////////////
p = 0;
this.onEnterFrame = function() {
filesize = picture.getBytesTotal();
loaded = picture.getBytesLoaded();
preloader._visible = true;
if (loaded != filesize) {
preloader.preload_bar._xscale = 100*loaded/filesize;
} else {
preloader._visible = false;
if (picture._alpha<100) {
picture._alpha += 5;
}
}
};

function nextImage() {
if (p<(total-1)) {
p++;
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[p], 1);
name_txt.text = name[p];
dimensions_txt.text = dimensions[p];
addinfo_txt.text = addinfo[p];
picture_num();
}
}
}
function prevImage() {
if (p>0) {
p--;
picture._alpha = 0;
picture.loadMovie(image[p], 1);
name_txt.text = name[p];
dimensions_txt.text = dimensions[p];
addinfo_txt.text = addinfo[p];
picture_num();
}
}
function firstImage() {
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[0], 1);
name_txt.text = name[0];
dimensions_txt.text = dimensions[0];
addinfo_txt.text = addinfo[0];
picture_num();
}
}
function picture_num() {
current_pos = p+1;
pos_txt.text = current_pos+" of "+total;
}

stop();

I am hoping to find a simple set of code that will tell the Flash to
load ALL the pictures referenced in the XML file just the same way it
loads between the pictures. So the preload animation will play only
once before the slideshow begins. I hope this helps.

link update if the initial posted link does not work: 

http://pellam.ucr.edu/~wfan/busanutenterprises/spaceprogram/slideshow.html

It's not a good solution prefer download only next picture for each
and calculate the time dowloading the next for set the inter image
delay.
