What's to switch? Obviously what you are doing right now has no incompatibility with AIR. You could just change the Flash setting to AIR and compile and get exactly the same result except that now you can write code to truly access any files in folders.
Maybe you have no experience with AIR and you think it's gonna be too complicated or you'll need to rewrite a bunch of code but that won't be the case. Just make the switch, compile, and see that everything is exactly the same just with more possibilities.

Yeah, i have try and it's nice to know...But i suppose my client will ask for web-site based on exactly same content...that's why i want to keep it strictly flash (universal), coz as i understand Flash player can't read some of AIR commands, like the one you suggested..
I just want to make something very universal, also for future projects, and it doesn't really matter how complex it will be

Hell...I still can't get it

This one should work fine as you said, but it loads only picture1 and trace of imagesURL array also shows only picture1...hmm
What i have missed?

// create an array of URLs
var imagesURL:Array = [];
// start URL counter
var index:int;
// create new loader
var loaderImages:Loader = new Loader();
// create container
var images:MovieClip = new MovieClip();

var pattern:String = "gallery/picture###.jpg";
var currentURL:String;
var currentNum:int = 0;
currentNum++;
currentURL = pattern.replace("###", currentNum);
imagesURL.push(currentURL);
trace(imagesURL);

// command to load
loadImage();

// function that loads image
function loadImage():void {
    // define image URL
    var imagesURLreq:URLRequest = new URLRequest(imagesURL[index]);
    // load image URL in loader
    loaderImages.load(imagesURLreq);
    // create listener so it would only execute loadNow function AFTER image is fully loaded
    loaderImages.contentLoaderInfo.addEventListener(Event.COMPLETE, loadNow);
    // set gallery loaded flag
    galleryIsLoaded = true;
}

update 1:
Now i think i get it!

var pattern:String = "gallery/picture###.jpg";
var currentURL:String;
var currentNum:int = 0;
loadNext();
function loadNext():void {
    currentNum++;
    currentURL = pattern.replace("###", currentNum);
    var loader:Loader = new Loader();
    loader.load(new URLRequest(currentURL));
    loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onNextComplete);
    loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onNextError);
}

function onNextComplete(e:Event):void {
    trace("loaded", currentURL);
    imagesURL.push(currentURL);
    loadNext();
}

function onNextError(e:IOErrorEvent):void {
    trace("stopped at", currentURL);
    trace(imagesURL);
}

Only thing left is to make some if statement, and i can't imagine how to do this...
I need to say somehow inside onNextComplete function, that if imagesURL array already got it's first URL than i need to call loadImage(); and this action must be executed only once...just to show first image, before other urls are pushed, coz it takes plenty of time to push all items...

update 2
Strange...but it take time only inside flash with ctrl + entere, in usual player it's fast..hmm

Also a big problem, that if name is picture01 or picture10 (anything that got "0") it fails to load...Why? Any suggestions?

[abeall]

"picture10" should work as is. "picture01" would not work because the number makes the url "picture1" not "picture01" -- you would need to add leading zeros.

This function will add leading zeros to a number:

function addLeadingZeros(num:int, minDigits:uint = 2):String {
    var str:String = num.toString();
    while(str.length < minDigits){
        str = "0" + str;
    }
    return str;
}

should work as is. "picture01"

done!
I was an idiot, haven't noticed that i put picture10 with .jpeg, not .jpg...

So, reasonable question is:
Is there a way to make function that would define if extension is .jpg .jpeg or .png?
something like that:
var pattern:String = "gallery/picture###.####";

but i guess this is either impossible, either very complicated, coz amount of characters could be 3 or 4 and there are letters, not numbers...

This is not very important, but this question is important:

Ok, i figured out the best suitable if statement

// function that adds URL inside an array
function onNextGalleryComplete(e:Event):void {
    // add current URL inside an array
    imagesURL.push(currentURL);
    if (currentNum == 1){
        // after first URL written inside an array - load it
        loadImage();
    }
    // load next URL
    loadNext();
}

It works!

But i found another heavy problem....When i test my movie in flash and emultate slow network speed, it write trace like this:

trace("stopped at", gallery/picture12.jpg);
trace("stopped at", gallery/picture13.jpg);

But i got actually 11 pictures, and it writes 12 inside an array...
Any way of getting past this kind of slow-speed errors?
