The link above ('http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=1|FE6256|000000') can't be used via SSL. To generate and store the number images locally:

for i in {1..99}; do curl -o ./${i}_map_icon.png  "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=${i}|FE6256|000000"; echo $i; done
