除一个问题外，此代码工作正常。代码生成小图像（默认博客缩略图大小为s72-c），无法自定义大小（将s72-c更改为s200 / s200-c / w200）。
我找到了一个针对Blogger的图片重新调整大小的解决方案脚本，但他们没有帮助。这是它
function resizeThumb(size) {
var popularPost = document.getElementById('PopularPosts1');
var image = popularPost.getElementsByTagName('img');
for (var i = 0; i < image.length; i++) {
image[i].src = image[i].src.replace(/\/s72\-c/g, "\/s" + size + "-c")
}
}
resizeThumb(200);
这是针对热门帖子小部件。我知道如果我在第一行更改ID，它将替换图像。但这不是解决方案，而是掩盖。这也意味着加载的两个图像是 s72-c 和被替换的图像。
我想在第一个相关的帖子脚本中集成它（类似这样）。我很努力，只有很少的javascript知识但我失败了。所以我注册了stackoverflow，这是我的问题。
提前感谢您尝试帮助我。

首先添加
var thumb = 200;
后
var thumburl = new Array();
然后
添加
thumburl[relatedTitlesNum] = thumburl[relatedTitlesNum].replace("/s72-c/","/s"+thumb+"/");
后
thumburl[relatedTitlesNum] = entry.media$thumbnail.url;
希望你喜欢它
