On my Nokia Lumia 520 I cannot open WhatsApp photos and videos. I deleted all other WhatsApp photos and videos but still I cannot view the images. What could be the reason for this?
Unless you accidentally deleted those images they should be in your WhatsApp folder. This folder is in SDCard > Pictures > WhatsApp. You can easily access this folder by downloading a Microsoft app called Files. With this app you can navigate to every folder and file in your mobile phone.
