Images Not Showing

Website: http://www.brescodiamonds.co.za/signature-jewellery

Hello, the images had stopped showing up, so I checked the settings page and it said I had to create an App and authorize it. I did that, and I’m not sure what I should do next, they’re still not coming up.

Could someone point me into the right direction?

Thanks!
