If you want to send a lot of binary data like an image to the server, I 
strongly suggest to upload the data directly to the server.

There is some internal upload management for the WebFileButton, but, 
alas, the browser prevents an upload button (<input type="file">) to 
trigger the upload without a user mouse click.

So I have to write some new code so that you can upload any data the 
server easily.
