Group 1 - The core issue is the unauthorized sale of wedding photos on second-hand trading platforms, which raises concerns about the infringement of portrait rights and copyright of photography agencies [1][2] - Many sellers are offering wedding photo packages at extremely low prices, with some listings showing 1200 images for less than 2 yuan, and even as low as 0.01 yuan [1] - The leakage of wedding photos can be attributed to poor management by photography studios, where internal staff may sell photos for profit or where security measures are inadequate, leading to unauthorized access [1][2] Group 2 - Photography studios have a responsibility to safeguard consumers' wedding photos and cannot evade liability by claiming ignorance or attributing the issue to third-party actions [2] - Online platforms must take proactive measures to monitor and manage the sale of wedding photos, implementing mechanisms for keyword recognition, price anomaly alerts, and content review to prevent infringement [2] - Consumers whose wedding photos are sold online should take immediate action to protect their rights, including contacting platform customer service, reporting to regulatory authorities, or pursuing legal action if necessary [3]
