    stack the images in an array, and access them like this

    MyXML[0].attributes.imageName
    MyXML[1].attributes.imageName

    etc...
    post some code from your XML doc, and ill give ya an example script

    Hey thanks for the reply! I got the images to load in correctly. I got the images to also scroll with the mouse movement. Now my problem is that whenever I move the mouse up then down (or vice versa) the images begin to whack out! Meaning, the alignment of the images begin to slip out of place...very strange! I'm sure it has to do with some sort of equation in the XML but I have no clue! Here is a link to what I have so far:

    http://www.tocquigny.net/temp_xml_scroller/

    Move the mouse to the top of scroll, getting it scrolling fast, hold it there for about 15 secs...then move the mouse to the bottom and do the same...you'll start to see the images begin to lose vertical alignment!

    ANY help would be greatly appreciated!!

    i seen what ur talking about.

    PHP Code:
    imageXml = new XML();
    imageXml.ignoreWhite true;
    imageXml.onLoad = function(success) {
        if (
    success) {
            
    menuItem this.firstChild.childNodes;
            for (var 
    i=0i<menuItem.lengthi++) {
                
    item scroller.image.attachMovie("imageClip""imageClip" ii);
                
    item._x 0;
                
    item._y 150*i;
                
    item.myImage menuItem[i].attributes.image;
                
    item.loadInto.loadIntoMain.loadMovie(item.myImage);
                
    menuItemLength menuItem.length 150;
                
            
    item.onEnterFrame = function(){
                
    yMousePos = -_ymouse;
                
    this._y += yMousePos/10;
                if(
    this._y>150*i){
                    
    this._y 0;    
                }
                if(
    this._y<0){
                    
    this._y 150*i;    
                }
            }
            
            }
        }
    }
    imageXml.load("myImages.xml"); 
    whats this line for?
    menuItemLength = menuItem.length * 150;

    Heh! I put that there thinking I was going to capture the height then scroll with it...actually that should be deleted or commented out.

    So what do you think? I really appreciate you looking at it.

    .length is used to return the length of a variable string.

    for example
    Jace = "happy"
    digits = Jace.Length

    trace(digits); would return the number 5

    alright, this is my guess as to whats happening here.

    you are evaluating the placement of each and every movieclip (image)that is displayed. Im sure if you only call in 3 or 4 images, those gaps wont happen. if you call in 100+ images, those gaps will be HUGE and the images will overlap and such. i think this is because your code is processor intensive. each clip that u duplicate contantly is checkin for its position using the onclip. so as you scroll up and down, any processor lag that occurs, offsets the true _ymouse value. since your function is using an evalualtion of the _ymouse, each clip is dependent on that value, and thus dependent on the processor speed.

    solution...

    duplicate the movieclip images INSIDE a larger movieclip. THEN scroll THAT larger one that contains all of the smaller ones. this will remove the need to reposition each image clip according to _ymouse because the scrolling is handled by the larger MC.
    so... try rewriting the duplication script to incorporate the image clip container.

    but before you do, try this first cause im not sure this is correct.

    PHP Code:
    u have
    for (var i=0i<menuItem.lengthi++)
    does menuitem.length return the number of childnode or the length of the string????

    maybe try this insteadits check to see if the value of the image NOT null.
    for (var 
    i=0menuItem[i].attributes.imagei++) { 
    hope this help alittle

    Hey Flash Nija I appreciate the help that may work and I'll try it. I emailed my buddy Robert Penner. (I hate bothering him) He got it to work in about 30 mins...he truly rocks.. Here is his solution:

    imageXml = new XML();
    imageXml.ignoreWhite = true;
    imageXml.onLoad = function(success) {
    if (success) {
    menuItem = this.firstChild.childNodes;
    for (var i=0; i<menuItem.length; i++) {
    item = scroller.image.attachMovie("imageClip", "imageClip" + i, i);
    item._x = 0;
    item.y = item._y = 150*i;
    item.myImage = menuItem[i].attributes.image;
    item.loadInto.loadIntoMain.loadMovie(item.myImage) ;
    //menuItemLength = menuItem.length * 150;

    item.onEnterFrame = function(){
    yMousePos = -_ymouse;
    switch (mspeed){
    case mspeed<1:
    mspeed=1;
    break;
    case mspeed>100:
    mspeed=100;
    break;
    }
    this.y += yMousePos*mspeed/100;
    if(this.y>150*i){
    this.y -= 150*i;
    }
    if(this.y<1){
    this.y += 150*i;
    }
    this._y = this.y;
    }


    }
    }
    }
    imageXml.load("myImages.xml");


    (I added the switch statment for my component)

    MANY props to Penner, once again.

    Thanks again FN!

    just for fun, copy and paste about 100 or so entries into your XML doc and see how the script runs. Im curious to see if moving 100 clips or so will slow or lag the script down.

    but cool

    Hey, I copied about 120 XML lines for 120 images and sure enough it slowed considerably. But I'm fine with that though, I really don't think people will load in 100 images into this thing. It's main purpose that I can see is a small portfolio section or navigation of some sort.

    Thanks for the help again.

    I'm sure there are some step by step instructions out there. I unfortunatly dont have the time put one together right now but I have created a quick example you can DLed form my site: www.monnone.com/stuff/fk_loadimages.zip

    This is a mutation from something I found a while back. I couldn't find it again so I don't know the original authors name so I can't give credit to that person. If you recognize this as yours then props to you!

    Anyway, study this set of files, you'll get, it's really not that hard at all. I stripped out all the unessasary BS code so you can learn from it!

    Good luck!
