Feature Slider Posts

Hi Sakin,   My website: aceit.ca Problems: First: I have 3 feature slider posts. When you click on each of them the pictures are not full sizes. It seems like they are cut off from the right side. Second: When you click on each picture, the site will take you to a page where you can post a comment, I would like to remove that. How do I go about it? Cause unchecking all the boxes "allow a comment" doesn't help and making the front page a static page doesn't help either.   Thanks for reply in advance.
