Vidic... just a few threads below this one, you'll see a boot called "Let's make a boot together" by some guy who claims to know how to make boots. That should help you. Photoshop is the preferred program, I'm not sure how well other image editing tools would do. As to quoting a post, all you need to do is to press the "Quote" button in the post you want to quote and then type your post beneath it.
Cheers!
