if your talking about the latest torrents carousel you might be on your own...
the 7.2 is still very encoded so the includes, required, etc may not be recognized. The mod is covered extensively in other threads and there are 2 of them and they both work. they should work as a plugin for your index.php simply by adding them to the plugin manager, simple enough, as far as extending it to your browse.php I am not sure it would read it, but if your a coder, or have one on staff it is something they can play with. Unless its been done away with there is a built in one in the tracker settings panel just enable it, set the number of torrent posters to show and tick the display with images and save, Then you can go to your plugin manager and place it anywhere on the index page that you want to.
