Best approach to displaying a scrollable grid of pictures in Flex Mobile App

In a Flex Mobile Application, I have a situation where I need to dynamically display a grid of like 50X50 pictures tha开发者_Go百科t can be scrolled though. The pics are stored in a mysql database.

I don't really know enough about the DataGrid or the TileLayout. Or if anyone knows of any other classes I should be reading up on to better solve this issue.

So, Basically like I said, I'm looking for any Flex/Actionscript-3 Class Ideas, examples, tutorials, ideas, feedback or anything to get me pointed in the right direction for this issue. I'm really stumped on how I can/should be doing this.

Simple enough:

<fx:DataGroup dataProvider="{yourImageURLs}" width="100%" height="100%"
   itemRenderer="yourCustomImageRenderer">
   <fx:TileLayout requestedColumnCount="2" />
</fx:DataGroup>

That should get you started.
