Do you mean you want to display a label with the name, and position the label above or below the image?
There are several ways to make the image larger upon mouse rollover.
You should probably start a new post for making the image larger upon rollover, so people searching the forum will be better served.
As for this post, I believe I have answered it.

If you want the images side-by-side, don't you want an HBox? Anyway, here's some code to answer your question.
The scrollbar won't display unless the images do not display within the HBox width. You can force the scrollbar to display always by setting the HBox horizontalScrollPolicy property to "on".
You might want to use a HorizontalList control instead.
Below I have hard coded indexes and also used a repeater in the HBox.
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
verticalGap="30">
<mx:Script><![CDATA[
import mx.collections.ArrayCollection;
[Bindable] private var imgs:ArrayCollection = new ArrayCollection([
{name: "red", path: "images/red.png"},
{name: "green", path: "images/green.png"},
{name: "blue", path: "images/blue.png"}
]);
]]></mx:Script>
<mx:HBox>
<mx:Image source="{imgs.getItemAt(0).path}"/>
<mx:Image source="{imgs.getItemAt(1).path}"/>
<mx:Image source="{imgs.getItemAt(2).path}"/>
</mx:HBox>
<mx:HBox horizontalScrollPolicy="on">
<mx:Image source="{imgs.getItemAt(0).path}"/>
<mx:Image source="{imgs.getItemAt(1).path}"/>
<mx:Image source="{imgs.getItemAt(2).path}"/>
</mx:HBox>
<mx:HBox>
<mx:Repeater id="rp" dataProvider="{imgs}">
<mx:Image source="{rp.currentItem.path}"/>
</mx:Repeater>
</mx:HBox>
<mx:HorizontalList dataProvider="{imgs}" columnCount="3">
<mx:itemRenderer>
<mx:Component>
<mx:Image source="{data.path}"/>
</mx:Component>
</mx:itemRenderer>
</mx:HorizontalList>
</mx:Application>

Hi,
its working fine, but i want to diaplay the name of the image on top or bottom of the image. i tried using the below code
<mx:Image name="{data.name}" source="{data.path}"/>
it did not work. what should i use?
Also can we add little bit of animation, like when i place the mouse pointer on an image it should pop out/or someway to highlight that user has looking at that particular image?
thanks
