GUIDE:

  1. Before use this script，make sure gallery switch to Large mode
  2. Click bottom right corner⋖📖⋗，enter into viewer mode
  3. Just a moment，All of thumbnail images exhibited in grid，click one of thumbnail images, into big image mode
  4. Image quality:level 1、thumbnail； level 2、compressed image； level 3、original image；
    In default config，auto load compressed image，with low traffic consumption with good clarity。also you can enable best quality in config plane, This increases the consumption of traffic and browsing quotas。
  5. Big image:click thumbnail image, into big image mode, use mouse wheel switch to next or prev
  6. Keyboard:
    Scale Imagemouse right + wheel or -/=
    Open Image(In thumbnails)Enter
    Exit Image(In big mode)Enter/Esc
    Open Specific Page(In thumbnails)Input number(no echo) + Enter
    Switch Page→/←
    Scroll Image↑/↓/Space
  7. Download:click download button，popup download plane，the loading status of all images is indicated by small squares.
  8. Feedback: Click Issue to provide feedback on issues, Give me a star if you like this script. Star

操作说明:

  1. 在使用本脚本浏览前，请务必切换为Large|大图模式
  2. 点击右下角⋖📖⋗展开，进入阅读模式
  3. 稍等片刻后，缩略图会全屏陈列在页面上，点击某一缩略图进入大图浏览模式
  4. 图片质量:图片质量有三档，1、原始的缩略图(最模糊)；2、E绅士的压缩图；3、原图；
    默认配置下，脚本会自动加载压缩图，这也是E绅士默认的浏览行为，具有较小的流量消耗与良好的清晰度。也可以在配置中启用最佳质量，脚本会加载原图，这会增加流量与浏览配额的消耗。
  5. 大图展示:点击缩略图，可以展开大图，在大图上滚动切换上一张下一张图片
  6. 键盘操作:
    图片缩放鼠标右键+滚轮 或 -/=
    打开大图(缩略图模式下)回车
    退出大图(大图模式下)回车/Esc
    打开指定图片(缩略图模式下)直接输入数字(不回显) + 回车
    切换图片→/←
    滚动图片↑/↓
  7. 下载功能:右下角点击下载按钮，弹出下载面板，内部通过小方块展示了所有图片的加载状态，点击开始下载按钮后，会加快图片加载效率并在所有图片加载完成后进行下载。
  8. 问题反馈: 点击 Issue 反馈你的问题或建议，如果你喜欢这个脚本，给我一个star吧。 Star
