"getImages()" is already defined into IPhotoFolder interface. But Philip

What I just mean (but perhaps I'm wrong) is that in my use case, the
"getSortedImages()" method is only used for presentation purpose in a
specific context, a specific browser view.
I think this kind of method shouldn't have to be defined in an interface
which main goal is to define generic content handling methods...
I don't know if my explanation is clear :-(
