Although I have not done it yet, I am told that it can be done. Of course you have to include the TRACKER and your KEY. I am not sure how images or descriptions or categories get attached. Perhaps AFTER the torrent shows up on this site, you can ADD those things later by editing the torrent. The last few times I attempted to use QTM, my torrents failed to complete the "backend" process.
I HAVE successfully used Utorrent to create torrents. Oddly, you do not even HAVE to specify a tracker (which is kind of scary since you have no control).
