Builds one person's signature for Street. Choose the branch and department, check the footer, fill in the person, add a headshot, then copy the HTML into Street. Street keeps its own copy of everything when you save, images included, so a signature already in Street never changes by itself: after any change (a new banner, a new photo, a new job title) make it again here and re-paste it.
Untick an image to leave it out, or move it up and down. The images themselves are set by the image library.
