D'oh!
The solution is so simple and clean that it almost hurts. I didn't see it in
the first approach!
There is a way to go all this, without using file() or file_get_contents()!
Cuz this would require to use a URL wrapper to retrieve compiled code, which
would cost overhead on the local webserver and the internet deamon.
Just use and modify this code. You may also put it into a function;
// I strongly recommend to use this INSIDE a function to get a clear
namespace
function get_img_script($parameters)
{
// backup $_GET variable
$getbuffer = $_GET;
unset($_GET);
$_GET = $parameters;
ob_start();
include 'yourscript.php';
$buffer = ob_get_contents();
Ob_end_clean();
// restore $_GET variable
unset($_GET);
$_GET = $getbuffer;
return $buffer;
}
And call it like this:
// define variables here. If you'd passed it with ?var=val
// use
$param = array('var'=>'val');
$img = get_img_script($param);
Hope that solves the problem in a clean way!

Use <?php phpinfo();?> to find out exactly what you've got.

If it's old enough, even file_get_contents may not be defined...
It first appeared in PHP 4.3.0, so if you're running something earlier
than that, upgrade.
Or I guess you could use:
implode('', file($filename));

This is doing rawurldecode() on $img twice, which is almost for sure
not right.
It probably "works" for all the actual inputs you are using, but it
would fail if somebody passed in a filename that happened to have
"%xx" in the actual filename, almost for sure.

This is using the Ming extension.
There is a Ming mailing list that may be helpful if it turns out that
$contents is fine, but the new SWFBitmap is "not working"
The number of Ming users is very tiny compared to PHP in general, and
I suspect not many hard-core Ming users are on this list.
