I have some code waiting to be merged that implements an
ImageCollection.  Typically, you'd have

ic = ImageCollection('*.png')

where all PNGs are access only as necessary, and are cached once
they've been read from disk.  You can also index into or iterate over
an ImageCollection (yielding the image arrays).  It sounds like a
multi-image could be interpreted as an ImageCollection.

OK, I'll implement this over the weekend.  If someone else has time,
feel free to jump in.
