Can't display .BMP graphics which is from smartforms in customer container

Hello Experts,

I have a question, I can't display .bmp graphics which created by class CL_IGS_CHART_ENGINE then to upload it into SAP system successfully, I imported it in a smartform. But, unfortunately, I can't see the graphics in the container but other objects in the smartform work fine when methed load_data called.

CALL FUNCTION l_fm_name
EXPORTING
output_options = i_output_options
control_parameters = i_control_parameters
i_graphics = i_grap_name
IMPORTING
job_output_info = lwa_job_output_info
job_output_options = lwa_job_output_options
TABLES
it_effi = lit_effi.

APPEND LINES OF lwa_ouput_info-xmloutput-trfresult-content[] TO r_value.

m_o_html_body_control->load_data(
IMPORTING
assigned_url = m_url_body
CHANGING
data_table = r_value ).

m_o_html_body_control->show_url( url = m_url_body
in_place = abap_true ).

Does any expert tell me how to fix it or what's the reason?

Thanks a lot !
