all the problems dealing with pictures that are taller than the visible window

[jidanni@xxxxxxxxxxx]

I have a 24 row tall window in emacs.
I try to view http://album.udn.com/yapcheahshen/photo/4019424
Holding down C-n, one discoverers
1) The L1 L2 L3... counter in the modeline freezes when upon the
picture, even though it is many lines tall.

When toggling images on, the line counter should reflect the images too.

2) Most frustratingly, when we get to the bottom of the picture, the
whole window jumps up etc.

Can "somebody" finally fix all the problems dealing with pictures that
are taller than the visible window?
