It's not about the picture, it the MAC address the units uses which will determine weather the unit is a "Clone" or, "Original". If the units MAC address starts with 00:12:25:xx:xx:xx it's a clone. IF it starts with 00:09:34 it's an "Original"
About the only danger to a "Clone" is running Gemini's images on it. Their later versions corrupt the units Boot Loader, forcing the user to recover it by re-installing the boot loader, with a J-tag cable.
