I hope you already got email setup on your note, then open email at bottom touch envelop icon with a plus. Type in whom to send then touch setting/option key next to home button (not the back key) choose attach file.... N hit send...
(Edit)
Or take a pic normal. Goto gallery select the pic (by long press) on top few icons will appear, one of them is like greater then sign (<) touch it, select email. then type in email address you want to send it. N hit send.
