I have this piece of code:

-------------------------------------------------------------------------------------------------------------------------

(hunchentoot:start (make-instance 'hunchentoot:acceptor :port 5000))

(push (hunchentoot:create-prefix-dispatcher "/" 'start-page) hunchentoot:*dispatch-table*)
(push (hunchentoot:create-folder-dispatcher-and-handler "pics/" "c:")
hunchentoot:*dispatch-table*)

(defun start-page ()
(cl-who:with-html-output-to-string (*standard-output* nil :indent t)
    (:html
     (:body
      (:img :alt "alt" :src "pics/pic01.jpg")))))

--------------------------------------------------------------------------------------------------------------------------------

and when I go to http://localhost:5000 I don't see a picture, I see alternative text "alt".

Why, where is the problem ?
