I know this is not possible, because mapserver uses timestamp...
but I don't sure...

yes is possible, you've to use $img->saveImage(''); instead of

$mapimageurl = $mapimage->saveWebImage();

and in your php page you've to use

header('Content-type: image/png');

if you use png format image, image/jpeg for jpeg etc...

I hope this can help
