You can also use table code if you wish. Not really needed for just two pictures, and not as flexible as HTML table code since SMF doesn't allow rowspan or colspan, but it does avoid the problem of run-on lines with the code, and can force two images to be on the same display line if their total width would normally cause the board to move the second one to the next line.
