You can disable K2 comments - go to any k2 element (items, categories, comments, any), then click on Parameters icon (next to trash icon) and go to comments settings - You can disable comments from that place.
Thank you very much I will do this now, also on this site when i look at it on IE the images are not appearing, I saw others have had this issue and I have tried to change the width from pixles to % and also checked that all the images work, but still nothing
