When you upload a torrent it will show up dead until you start the seeding.
You have to download your own torrent (the one you just posted), open it as you would any other but when you are asked to save it you point your torrent program to the exact file you created the torrent from.
Your torrent client should check the file and start seeding if all is well.
All right-thinking people have a thing for tighty whities :cheesy2:
A selection I grabbed from my database:
Below The Rim
Tailspin
Try Me on For Size
In His Dreams
New Pledgemaster
Out of Bounds
Winners
Powertool
Feast Your Eyes
I Do
The Young Cadets
Pizza Boy - He Delivers
Tighty Whities
De-Briefed
I don't know if any of them are here, you will have to do the search yourself. They all have at least one scene that features white briefs 
The easiest one I know is Media Player Classic (HC or earlier version)
All you have to do is open the movie, click on file/save thumbnails, decide how many thumbs you want and go. You may want to edit the suggested name because it adds all sorts of info to the name.
Oh, and it's free. And it is a good movie player
