What was done
PicasaPy is an open-source rewrite of Picasa 3.9 using Python and Qt. The project was reverse-engineered with Ghidra and developed with assistance from Claude and Codex.
PicasaPy is an open-source photo management and editing application designed as a modern successor to Google Picasa. The project aims to maintain compatibility with the original Picasa .picasa.ini file format, allowing both applications to interact with the same photo folders. According to the author, Virág Attila, the software was reverse-engineered using Ghidra and built with the assistance of Claude and Codex https://x.com/sanchomuzax/status/2115160045243814263. The application is implemented in Python 3.12+ using PySide6 and Qt Quick. While PicasaPy updates file modification times to trigger refreshes in Picasa, the author notes that the shared format does not support conflict-safe live synchronization, as Picasa may overwrite external edits during its own write operations. Development history shows extensive use of AI agents, specifically the picasapy-claude-agent, to refactor components and implement features. The project is licensed under GPL-3.0.
