On Windows 2000 Pro, the Microsoft IIS web server is crippled--it's 
limited to ten connections.  Apache is a separate web server, so it's 
not affected by this.

This is quite likely.

As someone else said, the usual trick on Unix is to upload the file 
under a different name, then rename it into place once the upload's 
complete.  In other words:

   * connect to FTP server
   * upload temp.jpg
   * rename temp.jpg to image.jpg
   * disconnect

(The connect and disconnect steps, of course, are optional--you could 
connect at the beginning and hold the connection open.)

File locking is a little more complicated on Windows (most Windows file 
locks are mandatory, and produce errors when you try to open a locked 
file; Unix file locks are usually advisory, and block until the file has 
been unlocked), but I would imagine this trick would still work.
