Q;Simplest as3 only example to upload images to flash

[eco_bach]

Hi
Can someone point me to a simple as3 amfphp example for uploading an image into flash from the desktop?
ie after uploading, the server should return either the path to the saved image OR a bytearray to display as in this example
http://www.sephiroth.it/tutorials/fl...php_bytearray/

Unless I am mistaken I have to somehow obtain a byteArray from the filereference object after browsing-selecting an image.
And then pass this bytearray to my remote service method.
Pretty sure I can use the same service used in the example link above, but need help scripting the front end.
