Something like this in your custom stylesheet ought to work:


(define %navicon-path% "icons/")

(define (gentext-en-nav-prev prev)
    (make empty-element gi: "IMG"
           attributes: '(("SRC" (string-append %navicon-path% "prev.gif"))
                        ("BORDER" "0")
                        ("ALT" "Prev"))))

(define (gentext-en-nav-next next)
    (make empty-element gi: "IMG"
           attributes: '(("SRC" (string-append %navicon-path% "next.gif"))
                        ("BORDER" "0")
                        ("ALT" "Next"))))

(define (gentext-en-nav-up up)
    (make empty-element gi: "IMG"
           attributes: '(("SRC" (string-append %navicon-path% "up.gif"))
                        ("BORDER" "0")
                        ("ALT" "Up"))))

(define (gentext-en-nav-home home)
    (make empty-element gi: "IMG"
           attributes: '(("SRC" (string-append %navicon-path% "home.gif"))
                        ("BORDER" "0")
                        ("ALT" "Home"))))


But I haven't tried it -- might have a booboo in the %navicon-path%
stuff...

Cheers,
Mark
