INSERT INTO gui element

From MapbenderWiki

This example SQL inserts the image <../img/button_gray/logo.jpg> into the GUI named my_gui at position 30 from the left border and 5 pixels from the top border.

INSERT INTO gui_element(fkey_gui_id, e_id, e_pos, e_public, e_comment, e_element, e_src, e_attributes, e_left, e_top, e_width, e_height, e_z_index, e_more_styles, e_content, e_closeTag, e_js_file, e_mb_mod, e_target, e_requires) VALUES('my_gui', 'logo', '0002', '1', 'Logo', 'img', '../img/button_gray/logo.jpg', '', '30', '5', '', '', '5', '', '', '', '', '', '', '');

To add elements comfortably or whenever you do not have direct access to the database server, use the web interfaces Edit GUI elements.
