Auto download images (when sender is not in contacts)

Is there a way to automatically download images from messages when the sender isn't in my contacts list?

I'm using WhatsApp Business on Android.

At the moment, I have to manually go into each message and click the image for it to download (I recieve approx 200 messages in a 10 minute time window)

I'm hoping there's a WhatsApp Business setting I've missed. But other than that, I'd be interested in a third party solution (such as a macro or auto clicker app). Cheers
