I wouldn't worry too much about the QUIT command. libUrl does this  
some time after a transaction is completed in order to close the  
session. But your log shows that the transaction didn't complete  
properly.

This is part of the log I see here when using more or less the same  
script as you.

TYPE I
200 Type set to I.
PASV
227 Entering Passive Mode (192,168,1,104,202,83)
STOR /Users/dad/Sites/image1.gif
150 Opening BINARY mode data connection for '/Users/dad/Sites/ 
image1.gif'.
226 Transfer complete.

Your log doesn't show a "226 Transfer complete" entry. This is  
important.

I'd guess that the source file in question might be empty. (It seems  
libUrl doesn't handle this situation too gracefully. I'll check that  
out later.) You could check by altering your script like this:

export image "image1" to file "C:/image1.gif" as GIF
put "ftp://name:pass@ftp.somewhere.com/image1.gif" into myURL
put "c:/image1.gif" into myFile
put url ("binfile:" & myFile) into tImageData
if length(tImageData) is 0 then
   answer "no data"
else
   libUrlFtpUpload tImageData, myURL,"uploadDone"
end if
