github.com/monero-project/monero-gu…bca/src/libwalletqt/Wallet.cpp#L659 Can anybody tell me why this line is in that function?

in my understanding there was anyway an outputs/keyimage exchange ahead of time, or I'm wrong?

Well practically I ask because I'm adding another method which should submit simply from a string instead reading from a file, obviously there is then no second string with the key images, and I would omit it because I think the view wallet would have no more information then on the outputs/keyimages exchange done before. Or I'm wrong?
