I have a string like this

,fotografie/prodotti/thumbs/000101.jpg,fotografie/prodotti/thumbs/000201.jpg,fotografie/prodotti/thumbs/000301.jpg,fotografie/prodotti/thumbs/000401.jpg,fotografie/prodotti/thumbs/000501.jpg,fotografie/prodotti/thumbs/000601.jpg,fotografie/prodotti/thumbs/000701.jpg,fotografie/prodotti/thumbs/000801.jpg,fotografie/prodotti/thumbs/000901.jpg,fotografie/prodotti/thumbs/001001.jpg

and i should :

- remove the first comma
- have any number of items ( i don't know how many) and add each URL into a different array's value
- iterate a loop to load the images, completing the code below


Thank You for your help
loader = new Loader();

loader.load(new URLRequest(IMAGEPATH));

loader.contentLoaderInfo.addEventListener(Event.COMPLETE, LOADNEXTIMAGE);

try this snippet

you'll need to replace the 'str' variable with your list of paths (i used 'a,b,c' for brevity) and modify the onComplete handler to do something with the thing you loaded (display it or store it or whatever)

var str = ",a,b,c";          // replace with your list of paths

var arr = str.split(",");    // turn the path string into an array, split at commas
 

/**

* load next image in queue 

*/

function loadNextImage(){

    // pop an item out of the queue, ignore blanks

    var path = "";    

    while(arr.length > 0 && path.length==0){

        path = arr.pop();        

    }

    if(path.length==0) {

       trace('nothing more to load');

       return;

    }

    

    trace('now loading ',path);

    

    var loader = new Loader();

    loader.load(new URLRequest(path));

    loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);

}
 

/** 

* callback for onComplete

*/

function onComplete(evt:Event = null) : void {

	// do something with what you loaded here

	

	// load next image

	loadNextImage();

}
 

// kick off

loadNextImage();
