Hi Baolu,
Yes it is possible.
I have a fairly large B&O logo on the 'Zones' screen, as there are only 3 buttons on this screen so there's nothing to cover up by mistake.
Just create a button and link the logo to it.
However, it can be a little hit or miss sometimes until you manage to get it to display. Adjusting the image size a little seems to work, though there seems to be little logic to whether or not it works at the moment.
Cheers,
Martin
