<h1>操作说明:</h1>
<ol>
<li>在使用本脚本浏览前，请务必切换为<a style="color: red" id="renamelink" href="${window.location.href}?inline_set=ts_l">Large|大图</a>模式</li>
<li>点击右下角<span style="background-color: gray;">⋖📖⋗</span>展开，进入阅读模式</li>
<li>稍等片刻后，缩略图会全屏陈列在页面上，<strong style="color: red;">点击</strong>某一缩略图进入大图浏览模式</li>
<li><strong style="color: orange">图片质量:</strong>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；<br>
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。
</li>
<li><strong style="color: orange">大图展示:</strong>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</li>
<li><strong style="color: orange">键盘操作:</strong>
<table>
<tr><td>图片缩放</td><td>鼠标右键+滚轮 或 -/=</td></tr>
<tr><td>打开大图(缩略图模式下)</td><td>回车</td></tr>
<tr><td>退出大图(大图模式下)</td><td>回车/Esc</td></tr>
<tr><td>打开指定图片(缩略图模式下)</td><td>直接输入数字(不回显) + 回车</td></tr>
<tr><td>切换图片</td><td>→/←</td></tr>
<tr><td>滚动图片</td><td>↑/↓</td></tr>
