Adding the branding is not tied to the processing of the maps. You can change the branding image as often as you like. It will just only be applied to paid maps or maps that are created on a subscription while the user's subscription is still active.
You need to host the image in the size you want it to be displayed. We think 150x50 or so looks pretty good. Transparency is good. You don't want to link to a 1000x1000 file or something like that.
