Where does WhatsApp store Images/Videos when Media Visibility is disabled?
In most devices, I have used WhatsApp creates a folder in internal storage. The folder for media files is /internal storage/WhatsApp/Media. It contains subfolders for images, videos, etc.

/internal storage/WhatsApp/Media/WhatsApp Images
/internal storage/WhatsApp/Media/WhatsApp Video
/internal storage/WhatsApp/Media/WhatsApp Animated Gifs
