Hmmm. That example is written using Flashr 0.3 which doesn't pass a 
ResultsSet to onPeopleGetPublicPhotos...

It is very old code in that example, your best bet may be waiting until 
I manage to get together my examples and tutorials for Flashr 0.5 
(hopefully over this holiday).

A movieclip is dynamic so you can add any properties you like to it. By 
setting mc.photo it means that when that clip is clicked on you can 
access the photo using this["photo"] in the button listeners.

This isn't necessarily the best practise way of doing things but I was 
trying to put all the code in one file to simplify the example. It does 
introduce some confusion with scope though...

Yes, in flash each movieclip has it's own set of depths. So the 
jpgHolder movie clip is attached at depth 1 within it's parent movieclip 
which is attached at a depth of i inside _target.

Hope they are helpful. It may also be worth signing up to the 
Flashcoders mailing list:
http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

To ask general questions about how flash and AS work - you'll probably 
get answers a lot faster there,

Cheers,

Kelvin :)
