Thanks tachyon, that helped some an you explained it very well, but I'm still having problems.
The problem is actually in opening the file to copy. If in the file box of the form I put in /path/to/myfile/on/the/web/server/pic.jpg rather than browse and grab a pic off of the hard drive of my Windows PC (C:\Documents and Settings) to upload to the webserver then it works great. BUt it won't open a file that is local. Any ideas? Do I need to be substituting the spaces in the windows file name first in order for it to be opened?
