Yeah, I _would_ have done that, but the images I've seen don't
actually contain the max number of pages in PageNumber[1].
Instead, they seem to contain PageNumber[0] + 1.
Here's an example from the file I sent (generated with IrfanView):

The PageNumber tag from the last IFD couldn't fit in the screenshot,
it's PageNumber[0] = 2 and PageNumber[1] = 3.
