This is not a toggle. This is unconditional refresh.

My concern is that previously C-u M-x org-toggle-inline-images would
"display links with a text description part". With your patch, it is no
longer the case because INCLUDE-LINKED is not affected by the prefix
argument.

And there is no clean way to allow INCLUDE-LINKED while keeping
consistency with latex preview commands.

What we might do here is making a new defcustom that will control
whether linked images should be displayed. Then, something like C-1
org-toggle-inline-images could toggle that defcustom and refresh all the
image previews in buffer (if any).

WDYT?
