Introduction

DSH Chat Image Lightbox

English | 中文


English

A DeepSeek Harness plugin that displays images inline in the chat with a lightbox overlay — zoom, download (save-as dialog), and prev/next navigation.

Features

  • Inline display: Images in AI responses render directly in the chat (via markdown ![alt](url))
  • Click to zoom: Click any image to open a full-screen lightbox
  • Download: Click the download button ⬇ to save the image (triggers browser save-as dialog for same-origin images)
  • Navigation: Left/right arrow buttons or keyboard arrows to switch between multiple images
  • Close: Click backdrop, press Escape, or click ✕ to close
  • Auto-enhance: MutationObserver automatically enhances new images added to the chat

Installation

Method 1: npm (recommended)

dsh plugin --profile desktop add @loyalchiiina/dsh-chat-image-lightbox

Method 2: Manual

  1. Copy the lib/ folder and cordis.patch.yml to your DSH profile's node_modules/@loyalchiiina/dsh-chat-image-lightbox/
  2. Add @loyalchiiina/dsh-chat-image-lightbox to your profile's package.jsondsh.profile.bundles array
  3. Restart DSH Desktop

Usage

  1. Place images in ~/.dsh/uploads/ (or any directory served by your DSH instance)
  2. In your AI response, use markdown image syntax:
    ![Description](http://127.0.0.1:<port>/images/your-image.jpg)
    
  3. The image will display inline with lightbox enhancement

Note: For the download button to trigger a save-as dialog, the image must be served from the same origin as your DSH instance (e.g., via the /images/ route). Cross-origin images will open in a new tab instead.

How It Works

ComponentDescription
Host (lib/index.js)Registers /images/ file-serving route and /api/image-gallery/list API on ctx.webServer
Client (lib/client.js)Uses MutationObserver to watch for <img> elements in the chat, adds click handlers that open a lightbox overlay

Requirements

  • DeepSeek Harness ≥ 2.0 (with webServer service)
  • Node.js ≥ 22

  • 下载:点击下载按钮 ⬇ 保存图片(同源图片弹出"另存为"对话框)
  • 切换:左右箭头按钮或键盘方向键切换多张图片
  • 关闭:点击遮罩层、按 Esc 或点 ✕ 关闭
  • 自动增强:MutationObserver 自动增强新加入对话的图片

安装

方式一:npm(推荐)

dsh plugin --profile desktop add @loyalchiiina/dsh-chat-image-lightbox

方式二:手动安装

  1. lib/ 文件夹和 cordis.patch.yml 复制到 DSH profile 的 node_modules/@loyalchiiina/dsh-chat-image-lightbox/
  2. 在 profile 的 package.jsondsh.profile.bundles 数组中添加 @loyalchiiina/dsh-chat-image-lightbox
  3. 重启 DSH Desktop

使用方法

  1. 把图片放到 ~/.dsh/uploads/ 目录(或 DSH 实例提供的任意目录)
  2. AI 回复中使用 markdown 图片语法:
    ![描述](http://127.0.0.1:<端口>/images/你的图片.jpg)
    
  3. 图片会内联显示并自动带 lightbox 增强

注意:下载按钮要弹出"另存为"对话框,图片必须从 DSH 同源路由提供(如 /images/ 路由)。跨域图片会在新标签页打开。

工作原理

组件说明
Host (lib/index.js)ctx.webServer 上注册 /images/ 文件服务路由和 /api/image-gallery/list API
Client (lib/client.js)MutationObserver 监听对话中的 <img> 元素,添加点击处理器打开 lightbox
