Theme Horse

@Lisa Can you provide a link to the same image page? I will have to link into it and see if this can be achieved. This is more of a feature coming from the WordPress itself.

@Lisa For now custom css could be the easier way to remove it. So, in the dashboard, go to Appearance->Theme Options->Design Options Tab->Custom CSS. Paste the following css and click on ‘Save all Changes’.

.single-attachment .comments-area {
    display: none;
}
