your set up instructions do not match the plugin set up screens. I am trying to change the word press logo out with mine in the admin bar. Maybe I am stupid but I can't figure it out. You show in you instructions a simple image replacement. In my plugin the only place I can see to do this is in the Admin Bar CSS Styles.
I see where it says to use
Style .ub_admin_bar_image to change styling of images in the admin bar
but you don't show the syntax of how I code for the image. If this is where I am to do this please give me a real world example.
