This looks like the perfect solution to me. Multi-page images have more of a 
document character but you'd expect them to be viewable in an image viewer, 
especially if you don't know about the multi-page propery.
Additionally it could be marginally useful to recognize multi-page (or 
explicitly fax?) TIFFs and open them in okular [e.g. if you click on them in 
konqi]. But this is probably hard to do as well as of doubtful usefulness.
