open a command promt window

cd to the directory of the uploader and type

uploader http://siteThatHasScript.net/cgi-bin/theirscript.cgi C:\uploadAllImages &inputname1=inputvalue1&inputname2=inputvalue2 2001 1

This will upload all the images in the directory, I allowed only for jpg and png
To change this you need to alter the script and recompile it. Or contact me if you need help to do this at admin@perlygates.net

2001 is the socket # and it will exit the script if there is not a socket listening on the machine the script resides on

Sockets are great for output to another progam that has executed the exe. You can send the bytes sent to a progress bar.
