向我的 Web 应用程序添加 gZip 压缩是否会提高加载大图像的性能？

我有一个 Web 应用程序，其中包含一个幻灯片放映，其中包含大约 10 张大图像 (100-200k) 图像。我听说有人过去使用 gZip http 压缩来帮助提高网站的性能，所以我开始对此进行一些研究。我最终发现下面的 web.config snipit 声称可以做到这一点：

<system.webServer>
  <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
    <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"/>
    <dynamicTypes>
      <add mimeType="text/*" enabled="true"/>
      <add mimeType="message/*" enabled="true"/>
      <add mimeType="application/javascript" enabled="true"/>
      <add mimeType="*/*" enabled="false"/>
    </dynamicTypes>
    <staticTypes>
      <add mimeType="text/*" enabled="true"/>
      <add mimeType="message/*" enabled="true"/>
      <add mimeType="application/javascript" enabled="true"/>
      <add mimeType="*/*" enabled="false"/>
    </staticTypes>
  </httpCompression>
  <urlCompression doStaticCompression="true" doDynamicCompression="true"/>
</system.webServer>

但是仔细观察后，这似乎对图像没有任何作用。

对图像 mimeTypes 使用 gZip 压缩是否有效，或者我是否会浪费时间将其添加到上面？谁能推荐任何改善大图像加载时间的好策略？

旁注：不确定这是否有什么不同，但该网站托管在 goDaddy 上。

I have a web app that contains a slide show with about 10 large images (100-200k) images. I've heard of people using gZip http compression to help improve the performance of their websites in the past so I started doing a little research on this. I ended up finding the following web.config snipit that claims to do this:

<system.webServer>
  <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
    <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"/>
    <dynamicTypes>
      <add mimeType="text/*" enabled="true"/>
      <add mimeType="message/*" enabled="true"/>
      <add mimeType="application/javascript" enabled="true"/>
      <add mimeType="*/*" enabled="false"/>
    </dynamicTypes>
    <staticTypes>
      <add mimeType="text/*" enabled="true"/>
      <add mimeType="message/*" enabled="true"/>
      <add mimeType="application/javascript" enabled="true"/>
      <add mimeType="*/*" enabled="false"/>
    </staticTypes>
  </httpCompression>
  <urlCompression doStaticCompression="true" doDynamicCompression="true"/>
</system.webServer>

But after looking at it a little closer this does not appear to do anything for images.

Is using gZip compression for image mimeTypes effective or would I be wasting my time to add it to the above? Can anyone recommend any good strategies for improving the load time of large images?
