if I were to use the "Go back" button, I'll just go back to the gallery.. which is fine if I'm not leaving a comment. But if I leave a comment I have to select the forum to take me to the terragen forum, then I can click their terragen gallery link to bring me back to the gallery of thumbnails. The "back to thumbnails" button doesn't take me back to the gallery if I'm leaving a comment, it takes me back to where I have to repost my comment.
