[PHP] best way to add spaces between those pictures?

[dani]

imagejpeg($recti5,'rectilinear5.jpg',50);
echo '*';
echo '<img src="rectilinear5.jpg"';

imagejpeg($recti6,'rectilinear6.jpg',50);
echo '*';
echo '<img src="rectilinear6.jpg"';


imagejpeg($recti8,'rectilinear7.jpg',50);
echo '*';
echo '<img src="rectilinear7.jpg"';

the echo+(space code in html)* is not working
