In March 2025, Chen Ziqiang developed a Markdown Image Slider Gallery extension for the xkcoding/md repository, enabling horizontal image galleries with captions and WeChat-compatible rendering. He designed a custom marked extension in TypeScript to parse specialized gallery syntax, ensuring accurate rendering of images and captions within Markdown content. By integrating this extension into the content rendering pipeline, Chen provided consistent output across different platforms. His work leveraged frontend development skills, including web components, CSS, and HTML, to address the need for richer image presentation in Markdown. The project demonstrated focused engineering depth in custom renderer implementation and cross-platform compatibility.
