[PHP] File Upload and ftp transfer problem

[Hugh Danaher]

I'm trying to get the following script to ftp transfer an uploaded image file so as to 
get around a file permission problem.  The upload portion of this works without 
problem, the ftp portion doesn't spit out any errors either, but the file transfered 
is just the name of the uploaded temp file and not the file itself.  
If I do a filesize() on $file_stream, I get 44K (the size of the image uploaded), I 
then transfer this var to the ftp function but what gets ftp and saved as a file is 
only 14 bytes.  The saved file has "/tmp/phpDcJSOq" as its entire contents. 
The upload scrip is below.
Thanks for any help to resolve this problem.
