Hi again,
this is just documentation for other users that may want to use the cam TAB in 2.8.1:
To get the graphics working, I replaced the "../../images...." links in the first UI file provided by Chris with only "images/" and copied the images subfolder of Chris second attachment (the archive) into my config directory.
ui file is attached. Can't include the images because the forum says. my attachment is to big... (although Chris could...)
regards
Domca
