The renderFooter would allow you to access the index of the array of images you feed it

from there you would be able to use the url and save it to your device upon providing some type of button to press to save

you can use 'react-native-fs' (https://github.com/itinance/react-native-fs) to download the image from a url in a temporary directory and then use CameraRoll to save it in your device properly (for iOS you have to do an extra step to make it work tho, search for how to set up CameraRoll in react native iOS)

That said, I will point out that renderFooter seems to be have been broken (I submitted a fix for it tho: https://github.com/ascoders/react-native-image-viewer/pull/324)
