So, in order to minimize the number of tacks, you need to arrange the pictures in a shape as close to a square as possible.  36 of the pictures make a 6 X 6 square, which takes 7 rows of 7 tacks to hit every corner, then you make another row of 5 pictures along any side of the 6 X 6 array and you add another 6 tacks.  Total of 55.\r<BR>\n" );
