Dynamic UIImage Content Loading in UITableView code?

[svveet]

Im trying to get a tutorial/sample code on how to dynamic download uiimage in uitableview. Just like native iTunes App loading artwork dynamically. its also called "lazy loading"

I have been searching it online for a while.

The only sample code that is available is
Open Kosmaczewski - Asynchronous Loading of Images in a UITableView
everything works great but it is too complicated to understand the code and it uses their own framework which i dont like.

Most people recommend the following link
An iPhone Developer's Blog iDevKit
but it is not available anymore.
Does anyone have the sample code from idevkit.com and is able to share to us?

or any others similar sample code? that would be great.
Thanks
