@knightgenetic easiest way (and actually what most uploaders do/prefer) is using an image hoster that can create auto-thumbnails with BBCode links (those links will direct the viewer to the full Image, like e.g. HD Trackers ask for)

E.g: imgbox.com or imagebam.com

imgbox.com is probably the best public hoster for images, very easy to handle - you can use square and full thumbnails with different sizes and name your gallaries, organize them and do basically everything you need.

both are used very often on many torrent sites, also if you want to upload e.g. e bluray to different HD Trackers you can easily use the same thumb BBcode again and again, making uploads much more comfortable.

short guide: sign up on imgbox.com -- you will find out the rest yourself, but make sure the site allows this hoster (but most should do, or have their own hoster with comparbela functions.
