writing a SWF out as a bitmap on server

I can figure out how to make a SWF into a bitmap using Bitmap & BitmapData classes but how do I transfer that bitmap representation or bitmap data into a file (jpg, bmp, png, etc.) on the server and what scripting language can handle that best? I've used PHP and think I can do it with that but I think for this project I need to use ASP.NET which I have no experience with. Is there an easy way to do this using ASP.NET and the .NET framework? thanks!

You can use JPGEncoder or PNGEncoder in the as3corelib to turn your bitmap into a jpg or png. From there, you could attempt to put that data into a multipart form submission using Loader, or you can send it through a socket connection, or (my preferred way), encode it with Base64 and send it as a normal String to be decoded on the server side.

I don't know the specifics of asp.net, but if it doesn't have a base64 decoder available, I'd be surprised.
