Obtaining product details from other shops

[irrelevant]

I'm working on a back-office module that needs to iterate through all products, whatever store they belong to by default, and get information about each as if it were being accessed in the context of (for now) the store that owns it.

 

I'm seeing a lot of inconsistency in the subroutines I'm trying to use - some will take $id_shop as a parameter, which is great; I can just pass $id_shop_default.  Some take a Context as a parameter, whichI think  I've managed to deal with.  Others don't have any way of specifying a shop, or appear to ignore the parameters. e.g. my current issue is with Product::getImages 

 

So. what's the best / proper way to access such things?  

 

Thanks
