Remove Author Picture from Posts

I was able to remove the author name but my theme has a specialized author intro attached to the posts. I was wondering how to remove the photo next to the post heading. If I could remove the date and comment graphic too, that would be ideal.

Here is my link:

Also, is there a way to create posts without dates…as in remove the 2015/06/10 within the web address? I know creating a page would do just that, but I need them to show up in my recent posts widget on the sidebar.

Thanks for the help.
