If WhatsApp is not saving Photos to iPhone, it is likely that you have not enabled or later on disabled the Save to Camera Roll option for WhatsApp Chats on your iPhone.
The default option in WhatsApp is to save photos to the Camera Roll on iPhone, which results in all WhatsApp photos attached to Chats being automatically downloaded and saved to the Camera Roll on your iPhone.
The other option is to Manually Save WhatsApp Photos to iPhone, which works only if WhatsApp has been provided with access to the Photos App on your iPhone.
Fix for WhatsApp Photos Not Saving on iPhone
If WhatsApp is not saving photos on iPhone and coming up with “Can’t save Photos to Camera Roll” message, you should be able to fix this problem using the following troubleshooting steps.

1. Go to Settings > WhatsApp > Photos > WhatsApp.
2. On the next screen, select All Photos option.
Now that WhatsApp has access to Photos App, you should be able to manually download and Save WhatsApp Photos to iPhone.

1. Open WhatsApp > tap on Settings tab in bottom-menu.
2. On WhatsApp Settings screen, tap on the Chats tab.
3. On the Chats screen, enable Save to Camera Roll option.
This will provide WhatsApp with the permission to automatically save photos to the Camera Roll on your iPhone.
