Hi I’ve been working on this photogallery for my site and i am a beginner level flash lover and i can’t really figure it out how to do it.  
I am trying to add to the flash movie a prev and next button and the gallery is made out of an xml gallery code that load externally the pics and the thumbs are loaded into a strip and the pics are loaded with the dinamic resize effetct…i can’t figure it out…here is the code:  
spacing = 10;  
containerMC.\_alpha = 0;  
pArray = new Array();  
pictArray = new Array();  
MovieClip.prototype.loadPic = function(pic) {  
this.\_alpha = 0;  
this.loadMovie(pArray[pic]);  
this.\_parent.onEnterFrame = function() {  
var t = containerMC.getBytesTotal(), l = containerMC.getBytesLoaded();  
bar.\_visible = 1;  
per = Math.round((l/t)_100);  
if (t != 0 && Math.round(l/t) == 1 && containerMC.\_width != 0) {  
var w = containerMC.\_width+spacing, h = containerMC.\_height+spacing;  
border.resizeMe(w, h);  
bar.\_visible = 0;  
delete this.onEnterFrame;  
} else {  
bar.\_width = per;  
}  
};  
};  
MovieClip.prototype.resizeMe = function(w, h, pic) {  
var speed = 3;  
this.onEnterFrame = function() {  
this.\_width += (w-this.\_width)/speed;  
this.\_height += (h-this.\_height)/speed;  
if (Math.abs(this.\_width-w)\<1 && Math.abs(this.\_height-h)\<1) {  
this.\_width = w;  
this.\_height = h;  
containerMC.\_x = this.\_x-this.\_width/2+spacing/2;  
containerMC.\_y = this.\_y-this.\_height/2+spacing/2;  
containerMC.\_alpha = 100;  
delete this.onEnterFrame;  
}  
};  
};  
my\_xml = new XML();  
my\_xml.ignoreWhite = true;  
my\_xml.onLoad = function(success) {  
if (success) {  
for (var i = 0; i\<this.firstChild.childNodes.length; i++) {  
pictArray.push(this.firstChild.childNodes_.attributes.thumb);  
pArray.push(this.firstChild.childNodes\*.attributes.image);  
}  
}  
delay = setInterval(makeMenu, 100);  
};  
my\_xml.load(“gallery2.xml”);  
var menu = this.createEmptyMovieClip(“menu\_tot”, 99);  
menu.setMask(mask);  
var sub\_menu = menu.createEmptyMovieClip(“menu”, 100);  
var p = 0;  
var q = 0;  
var loadper = 0;  
function makeMenu() {  
clearInterval(delay);  
var item = sub\_menu.createEmptyMovieClip(“pic”+q, q);  
item.loadMovie(pictArray[p]);  
var temp = \_parent.createEmptyMovieClip(“tmp”, 9999+q);  
temp.onEnterFrame = function() {  
var tot = item.getBytesTotal();  
var loa = item.getBytesLoaded();  
var per = Math.round(((loa/tot)_100)/(pictArray.length_2));  
loadBar.\_xscale = loadper+per;  
if (tot == loa && tot\>4) {  
item.id = p;  
loadper += per;  
if (q\>0) {  
item.\_x = sub\_menu[“pic”+(q-1)].\_x+sub\_menu[“pic”+(q-1)].\_width;  
} else {  
item.\_x = 0;  
}  
item.onRelease = function() {  
containerMC.loadPic(this.id);  
};  
nextItem();  
delete this.onEnterFrame;  
}  
};  
}  
var amount = pictArray.length-1;  
function nextItem() {  
if (q\<((pictArray.length_2)-1)) {  
q++;  
if (p\<(pictArray.length-1)) {  
p++;  
makeMenu();  
} else {  
p = 0;  
makeMenu();  
}  
} else {  
activateMenu();  
}  
}  
var center = Stage.width/2;  
var speed = .05;  
function activateMenu() {  
menu.onEnterFrame = function() {  
var distance = \_root.\_xmouse-center;  
if (mask.hitTest(\_root.\_xmouse, \_root.\_ymouse)) {  
this.\_x += (distance_speed);  
if (this.\_x\<-sub\_menu.\_width/2) {  
this.\_x = 0;  
}  
if (this.\_x\>0) {  
this.\_x = -sub\_menu.\_width/2;  
}  
}  
};  
}  
Thanks anybody that can help me and explain to me where to put the code and how should i call these functions.  
Also ,if anybody knows, i wanna know if is possible to make a gallery that is made out of an infinite thumb strip and everytime i click on one it will load the resized effetct pic right into the infinite strip gallery …with the easing effect.  
I don’t know if is possible.  
Another question about the code i posted is that i wanna stop the infinite thumb action everytime i click on a thum pic , and when i roll over another thumb i’d love for the infinite menu to start his action again.  
I know is not easy and for me is very hard to do this stuff because i usually do it once a year (or when i feel like changing my site ) so my knowledge of flash is just basic and this is just a passion that i have and if is possible and anyone can explain to me why doing certain moves it would help a lot more than just the answer.  
Anyway sorry 4 the long email and the bad english(not my main language) if anyone could help i would really appreciate.  
Thanks a lot  
Massimo
