Replacing the Zoomify logo is quite simple with the HTML parameter zLogoCustomPath=logoPath. This example uses a small graphics file named 'toolbarLogoCustom.png' in the folder 'Assets/LogoCustom/'. (Note that replacing the logo is permitted only in the Pro and Enterprise editions. Hiding the logo is possible in Express, Pro, and Enterprise editions using the zLogoVisible=0.) See the Zoomify Parameter List in the Documentation folder for details.
