My camera is a Canon PowersShot SD1100 IS

And I cant find my cd to install the program on the computer or whatever (I must do this because we reloaded our computer) So Its not letting me load my pictures on the computer, is there some way I can download this cd from the internet? What should I do!

THANKS FOR YOUR HELP!
