Hi -
You could try running Rhino from a desktop shortcut with the /nosplash argument.
Note that it’s not the downloading of that picture that is taking time. You might be running plug-ins that need to initialize and there’s always the communication with the license server that needs to happen (unless you are running in stand-alone mode).
You could try running with the -stopwatch argument on a shortcut to check what is taking time.
There’s more information on all of this in several other threads around here, such as this one:
