I'm not sure I understand the implication: that I could achieve what I'm after 
by wrapping the images in a function?  I'm not clear on how that would work.

This sounds like it might be the kind of thing I'm after.  Given that I don't 
necessarily know how the images are being created, could attaching such a 
property be done without changing how the image%s are instantiated?
