In a Lightning Network HTLC, the sender of the payment provides the pre-image to the recipient. The pre-image is used to prove that the recipient has received the expected amount of funds, and that the sender is in control of their private keys. Once the recipient has the pre-image, they can then use it to claim the funds from the Lightning Network.
