I want a logo separate from the header title

I’m using the Parament theme. I want to install a logo in the top right hand corner of my pages, separate to the header title. I have installed a plug in to do this, but it can only be installed in a side bar, as parament doesn’t have a header bar to manipulate? I do not want the logo to take up the entire header, nor be a featured image, just a small logo in the top right hand corner.
