Use Image for Entry or Page Title

I apologize in advance if this question has already been answered – my searches didn’t really lead anywhere.

What I want to do is allow the user to upload an image for their entry that will act as part of the entry title (as on https://www.blind.com)

If the user just uploads an image, it will be inline with the rest of the entry, which is not what I want. I want it to be a headline image that spans the width of the Title DIV. If they just upload an image it will fall in the padding of the content DIV. At least…that’s how I’m setting up my CSS document.

I’m assuming I’ll need a plugin to accomplish this?

Thanks all in advance! I appreciate everyone’s help.
