how to generate screenshot/thumbnail (take photo) on swf files

I'm writing arcade game script. i want to take a photo for thumbnail on swf files.

have php got function for this? Or How difficult?

1. Upload a swf file
2. Take a photo uploa开发者_JAVA技巧ded file
3. Move directory
4. Add to mysql

That's not possible with PHP alone. The best solution in my eyes is to use a browser screenshot tool on a page that embeds the flash.
