first time image is not displayed in container

actual requirement is, to capture image from webcam then displayed it in module pool container.

for this, my approach as below

1. start webcam and take image.

CALL METHOD cl_gui_frontend_services=>directory_list_files
         EXPORTING
           directory                   = lv_dirname
           filter                      = '*.bmp'
           files_only                  = 'X'
*         directories_only            =
         CHANGING
           file_table                  = dl_files
           count                       = dl_cnt
         EXCEPTIONS
           cntl_error                  = 1
           directory_list_files_failed = 2
           wrong_parameter             = 3
           error_no_gui                = 4
           not_supported_by_gui        = 5
           OTHERS                      = 6.
       IF sy-subrc <> 0.
* Implement suitable error handling here
       ELSE.
         SORT dl_files BY createdate DESCENDING createtime DESCENDING .
         READ TABLE dl_files INTO ll_files INDEX 1.
         IF sy-subrc EQ 0.
           gi_filename = ll_files-filename.
           CONCATENATE lv_dirname  gi_filename INTO gi_filename.
           CONDENSE gi_filename.
         ENDIF.
       ENDIF.

2. upload image to sap

  gi_name = gv_driver-license."LS_TOKEN_DET-token.
   gi_object = 'GRAPHICS'.
   gi_id = 'BMAP'.
   gi_btype = 'BCOL'. "If u want black and white pass BMON
   gi_resident = ' '.
   gi_autoheight = ' '. "'X'.
   gi_bmcomp = 'X'.
*  gi_resolution = 200.
*l_width_pix = '400'. "'474'.
*l_height_pix = '400'. "'356'.
   l_extension = 'BMP'.

   PERFORM import_bitmap_bds IN PROGRAM saplstxbitmaps USING gi_filename
   gi_name
   gi_object
   gi_id
   gi_btype
   l_extension
   ' '
   gi_resident
   gi_autoheight
   gi_bmcomp
*l_width_pix
*l_height_pix
   CHANGING l_docid
   gi_resolution.

3. display image

CREATE OBJECT:
     container EXPORTING container_name = 'PIC10',
     picture EXPORTING parent = container.
     lv_obj =  gv_driver-license.

     CALL METHOD cl_ssf_xsf_utilities=>get_bds_graphic_as_bmp
       EXPORTING
         p_object       = 'GRAPHICS'
         p_name         = lv_obj
         p_id           = 'BMAP'
         p_btype        = 'BCOL'
       RECEIVING
         p_bmp          = l_graphic_xstr
       EXCEPTIONS
         not_found      = 1
         internal_error = 2
         OTHERS         = 3.
     IF sy-subrc EQ 0.
       graphic_size = xstrlen( l_graphic_xstr ).
       l_graphic_conv = graphic_size.
       l_graphic_offs = 0.
       WHILE l_graphic_conv > 255.
         graphic_table-line = l_graphic_xstr+l_graphic_offs(255).
         APPEND graphic_table.
         l_graphic_offs = l_graphic_offs + 255.
         l_graphic_conv = l_graphic_conv - 255.
       ENDWHILE.
       graphic_table-line = l_graphic_xstr+l_graphic_offs(l_graphic_conv).
       APPEND graphic_table.
       CALL FUNCTION 'DP_CREATE_URL'
         EXPORTING
           type     = 'IMAGE'
           subtype  = 'X-UNKNOWN'
           size     = graphic_size
           lifetime = 'T'
         TABLES
           data     = graphic_table
         CHANGING
           url      = url.
       CALL METHOD picture->load_picture_from_url
         EXPORTING
           url = url.
       CALL METHOD picture->set_display_mode
         EXPORTING
           display_mode = picture->display_mode_fit_center.

     ENDIF.
     CLEAR :url.

   ENDIF.

4. call picture_display in PBO

      PROCESS BEFORE OUTPUT.

       module picture_display.

here picture is displayed from second time onward, but first time picture not displayed. i have also check whether picture in uploaded before display, it uploaded (check it in SE78). please help its urgent.
