Can't find a good tutorial on this

Anyone know where I can find a tutorial and or code (AS3) for the following:-
A photo gallery powered by an external XML. I know there are loads of these! but I want it to be specifically interactive with buttons for navigating to a specific image not just next or back buttons. I don’t want to use components such as ‘list’ or ‘tile list’ UI list. I want to make my own buttons.

Thanks
