title: PHP: How to split a blob-picture in nine parts?
body: <p>I got a real hard question now: I have a blob-Picture saved in my database. Now, I want to split it into 9 Parts (like the tic-tac-toe-grid) and then I want to hide the one down right. Now I want to display these 8 parts in a random order, so you can move them and solve the puzzle (the moving could be solved with javascript).</p>
  
  <p>How can I make the php-functionality? Are there existing functions for that?</p>
  
  <p>Thx for help ;)</p>
