I’ve written a tutorial which is published over at flash.tutsplus. This tutorial demonstrates how to create a horizontally scrolling image viewer and covers xml parsing, loading and resizing external images, and creating intuitive and responsive scrolling!
So check out the Tutorial to Create a Responsive Image Scroller in ActionScript 3.0 over at flash.tutsplus.com!
You’ll find full source code available for download as well as the demo files and step by step milestones all throughout the tutorial.
!!!! thank you

hi. i am going to copy/paste the post i posted on flashtuts, maybe you can help me:
“hello,
very nice tut, very well explained. i do have one question. let’s say i already have created a ’scroller’ which has a nice look, and i’ve already placed some containers for thumbnails in the scroller. what would be the simpliest code to load pictures from xml into those specific containers? (everything else, including movement is done separately)
i will start with this:
var xmlLoader:URLLoader = new URLLoader();
var xmlData:XML = new XML();
var xmlPath:String = “pictures_xml.xml”;
xmlLoader.load(new URLRequest(xmlPath));
this part is enough for loading the xml, correct? (let’s say that the pictures are small enough so i will not need the complete event listener.)
what i need now is to put the infos from xml into my scroller and make so that when i press one image i got the big one loaded into a different container. and here i got stucked.
can you, please, help me? you can name however you want the containers and the scroller.
thanks you very much,
alex”
Hii all, I m going to perform a Drag and Drop intractivity using ActionScript 3.0.
I m going to perform drag n drop of images which are loading into a movieclip and then i m trying to apply the drag n drop logic but i m facing a trouble as loader class is used in loading external images and startDrag() and stopDrag() method cannot be applied on loader type object it should either be applied on a movieclip object or on Sprite type object. Here is my source code that i m working on. Please help me as soon as possible :

@Prateek -
You solved it already basically, just put the loader into a container movieclip and then you’ll be able to apply the drag and drop logic to them. That or you can re-parent the contents of the loader object to any display object on loadcomplete and it will rid you of the loader object altogether.
Hi,
The tutorial and the source code is not available in the link you gave. pls check it. infact there is nothing showing if i type flash.tutsplus.com
It’s actually changed to active.tutsplus.com – funny they dont redirect or anything. Thanks for finding it, I’ll update the link.
This is very useful.
I just had one problem, while trying it.
What if the images I have has different “width”, and I don’t want it to be in the “box” (say in here 140), and I just want the space between the images is the “padding”.
I hope you can help.
Thanks again.
How can I make this into a vertical slider?
