upload via delphi, simulate browse file in firefox

I'm using the custom components in my web framework as below

the purpose of the multiple is to crop, rotate and automatically upload to the server.

so can I make a tool to simulate the click and automatically upload everything in the path c:\scan on button click in delphi form?

Please note that I don't have a problem with the uploading from delphi a single file directly to PHP file, but in my situation I need the action client to client and continue the process by the user when press Save in the Web Page.

Regards
