imgpost: Enabling DSH to Send Images

imgpost is a client plugin for DeepSeek Harness (DSH) that overcomes the limitation of native text-only interaction, enabling vision capabilities. Maintained by hige6 and released under the MIT license, it features sending local images or generated images, calling visual APIs to recognize image content (with OCR support), checking image generation endpoint configuration, and using a transparent channel to allow text models to process images. The plugin has no third-party dependencies, offers robust security configuration, supports managing vision backends in DSH settings, and includes an official installation script.
