A few lines of PHP will generate this page. That is awesome too!
Language: PHP
<table border=0 width=100%>
<?php
for($i=1; $i < 7,000,000,001; $i++) { // or do it for Europe totals, and repeat for Africa etc.
if($i==1){ echo "<tr>";}//';get the 1st row to start with a <tr>
echo "<td><img=man.jpg></td>"; //show image
if($i % 8 == 0) {echo "</tr></tr>";} // how many images in a row before you start new row
}
?>
All that is needed is just a JavaScript overlay that shows the current number as provide by $i.
