dsh-image-pathify: Enabling DSH models without image capability to process chat images

dsh-image-pathify is an MIT-licensed plugin for DeepSeek Harness (DSH) Web, designed to address the need for models that cannot directly process images (such as deepseek-v4) to understand images in chats. By replacing images with local file paths before sending a message, the plugin prompts the model to invoke the built-in `analyze_image` tool to obtain textual descriptions using the configured OpenAI-compatible vision API. It supports passing multiple images at once and maintains original behavior for models that already support image recognition without exposing the relevant tools. Installation is simple: run `dsh plugin add dsh-image-pathify`, start the Web interface, and then configure the API key, vision model, and interface address in the settings page.
