The arrows show the direction of electron movement. For an example, in the first step, the electrons on Oxygen are donated to the H+ ion. Hence, the arrow is from Oxygen atom to H+ ion. Following is the diagram showing the arrow-pushing mechanism. The Initial product and the final reactant have been taken from the image you have linked while rest of the mechanism showing arrows (in red) are drawn in the figure below.
