I have a customised logo that I need to insert on the blog instead of the title. I want to keep the tagline. I've resized the image so that it is 100px high. The URL to the image in the media library is http://wp.me/a3biyG-1E.
I am new to coding (i.e. complete novice!) so would really appreciate any help with this.
The blog I need help with is immunoad.wordpress.com.
