I am crazy now. In fact, each tif file is just one page, but if there 
are in the same folder, then the Gnome Eye will treat them as one page 
with multiple files inside. i.e., if I have b1,b2,b3 and b4 then open b1 
will show that b1 has 4 pages. If I delete b2, b3 and b4, so it opens b1 
as one page !!!!!!!
