Wrote a small debug class that takes a screen dump of the stage and puts the file on a server (PHP).

So put this PHP on a server somewhere.

<?php
$png = $GLOBALS["HTTP_RAW_POST_DATA"];
$name = date('Y-m-d H.i.s');
$filename = $name.'.png';
file_put_contents($filename, $png);
?>


Then you can add this class to you project, required is the adobe core package (http://code.google.com/p/as3corelib/).
Download Screendump.as

To use it first set the URI and stage
Screendump.stage = this.stage;
Screendump.URI = “http://localhost:8888/screendump/dump.php”;

After that whenever you need to take a dump, run
Screendump.takeDump();
