The sender believes that the lack of authentication may be an inherently unsolvable problem given the current technological constraints. For further information or to address these concerns, the sender has provided a link to their personal website (https://petertodd.org) and an email contact, which appears to use Python list slicing syntax to partially obfuscate the address: 'peter'[:-1]@petertodd.org.

In addressing the first issue, it is implied that a solution is sought to incorporate images effectively into the project. On the other hand, the second issue regarding authentication presents a more challenging obstacle. The sender suggests resignation to the possibility that with the tools at their disposal, creating a secure authentication mechanism may not be feasible. This points to a potential need for either accepting the limitation or seeking alternative technologies or methods that could provide a solution.
