Yes, sorry.  When you are using image-dired, there is a header line with
some informations (by default name of the file, its size and so on, see
`image-dired-display-properties-format').  Those informations are
updated when you move from one thumbnail to another (by mean of
C-{f,b,n,p}).  But they are not updated with C-v/M-v.  This patch fixes
this.

(BTW "tracking" is not the correct word here as it means something else
in image-dired)
