hi aftab,
where is your pic stored ? if it is in local system..then you have to upload the picture using FM and it will store in STXBITMAPS then do display it in smart forms.
if it is custom table then i don't think smartforms will not work out easily,instead you have to try adobe forms..

hope it helps...
