I don't know what the convention is either, but I would borrow from thumbs.el:

(defcustom thumbs-thumbsdir "~/.emacs.d/thumbs"
  "*Directory to store thumbnails."
  :type 'directory
  :group 'thumbs)

(defun thumbs-thumbsdir ()
  "Return the current thumbnails directory (from `thumbs-thumbsdir').
Create the thumbnails directory if it does not exist."
  (let ((thumbs-thumbsdir (file-name-as-directory
                           (expand-file-name thumbs-thumbsdir))))
    (unless (file-directory-p thumbs-thumbsdir)
      (make-directory thumbs-thumbsdir t)
      (message "Creating thumbnails directory"))
    thumbs-thumbsdir))

etc...
