Using a different size requires handling it at different levels: how to
specify the size interactively (like a prefix option you proposed above),
how to specify the size statically (with an user option), where to save
thumbnails with different sizes (use some file name convention).

I think it would be good to add a new user option with an alist with the
size-to-geometry mapping where "size" is a subjective word describing
an approximate size:

'(("Very small" . "32x32")
  ("Normal" . "128x128")
  ("Large" . "256x256"))

For example, the Gimp uses the following vocabulary for the size words
describing the preview sizes:

Tiny
Very small
Small
Medium
Large
Very large
Huge
Enormous
Gigantic

I like to add two new user options for this:

(defcustom tumme-dired-thumb-relief 0
  "*Size of button-like border around thumbnails in dired buffer."
  :type 'integer
  :group 'tumme)

(defcustom tumme-dired-thumb-margin 1
  "*Size of the margin around thumbnails in dired buffer."
  :type 'integer
  :group 'tumme)

Their default values 0 (relief) and 1 (margin) seems good to me.
