[Theme: Responsive] Custom post in Homepage

Hi, I have a question regarding the responsive theme and its home page. If I override the WP homepage with the responsive homepage (located in theme options) I have 3 widgets and a block that contains “hello world” with a picture next to it. I want the “hello world” block to be empty so that I can place my own picture and a slideshow (with short code) in that specific location, but I don’t know how to do such thing. I hope anyone can help me out and tell me how I do this. Thanks.
