Looking at the code, there seems to be no way to change the width of the
box that's drawn around images (when the cursor is on them).  You can,
however, change the colour.  I use a red cursor myself:

(setq default-frame-alist
      (nconc (list '(mouse-color . "red")
		    '(cursor-type . box)
		    '(cursor-color . "red"))
	     default-frame-alist))

Hm...  I don't think Emacs has any built-in functionality for doing
that.  I think you'd have to create a new image that has the border you
want, and then composite the thumbnail onto it.
