Not sure why the regex isn't working for you, I copied the base64 post data and your code and it worked fine. You can try this instead which doesn't use regex and may be a little faster and use less memory.

$imgstr = $_GET['imgdata'];

list($type, $imgstr) = explode(';', $imgstr);
list(, $type)        = explode(':', $type);
list(, $imgstr)      = explode(',', $imgstr);
$content = base64_decode($imgstr);
