Header picture and Logo picture

I have the Unlimited theme. I’ve tried to add header picture going to appearance – customize – header image. The only option I get is to spend $49 for unlimited Pro Plugin. No other option is provided. Is there another way to upload header picture?

So then I tried to upload logo in the header. Appearance – Logo. When I upload the small logo it makes the website name disappear. All that shows is the logo and the tagline but not site name. Any help there?
