网站里的图片应该如何优化

以下是对网站图片优化的一些技巧： 1. 文件格式：选择合适的文件格式，比如 JPEG、PNG 或 GIF。JPEG 适用于照片和复杂图像，PNG 适用于简单图像，如图标和标志，GIF 将动画和卡通和简单的图像呈现得很好。 2. 图像压缩：使用压缩工具，如 Photoshop 的 Save for Web 功能，来压缩图片并减小文件大小，以便更快地加载。 3. 图片尺寸：使用适当的尺寸显示图片。不建议使用小图缩放到大图，这样会导致图像失真并增加文件大小。 4. 图像标记：在图像标签中使用关键字和描述，以提高搜索引擎的可访问性，并帮助网页排名。 5. 图像缓存：使用缓存插件或组件，如 WP Super Cache 和 W3 Total Cache，以优化和提高网站的加载速度。 6. CDN 加速：使用 CDN（内容分发网络），以帮助加速加载速度，并减少图片请求的数量。 7. WebP 格式：对于 Chrome 网络浏览器，使用 WebP 格式的图像，这可以大大减小文件大小和提高网站的加载速度。
