$base=$_POST["image"]; $binary=base64_decode($base); $file = fopen("image.jpg", "w"); fwrite($file, $binary); fclose($file); 

Answer 1

You need to open the file in binary mode ...

 $file = fopen("image.jpg", "wb"); 

Answer 2

Try the imagecreatefromstring() function: http://us.php.net/manual/en/function.imagecreatefromstring.php

(the example on this page is very similar to your code)
