Actually, it does.  That's why NSImage can load any image file type
that Quicktime understands.  What's probably tripping Josh up is that
NSBitmapImageRep will try to decode *some* image types itself, tiff
being among them.

Josh, what errors are showing up when you try to load the image?  Does
the image show up if you try to drag it into an NSImageView in
Interface Builder's "test interface" mode?
