Adding Flash file with url link

Hello!

Can you tell me if it's possible to add Flash file where the GET variable will be sent?

For example, Myflash.swf?url=mylink

I use this line for adding Flash:

list($ret,$item) = GalleryCoreApi::addItemToAlbum($file, $filename, $text, $text, $text, "application/x-shockwave-flash", $albumId);

But I don't know how to send variable.

Thanks!
