How to support 3rd Party image in blogspot recent post with below js code?

I use the following code for recent posts on my blogspot site.

When I upload a new image to my blog, most of the time the images are uploaded via a link like https: //1.bp.blogspot.com / ......

But sometimes when uploading pictures, the pictures are uploaded by such links as https: //blogger.googleusercontent.com/img/a/A ......

Then my pictures are not clear on the home page. And the pictures come at length. I did a Google search and found that the code below does not support third party images.

So I want to know how I can support third party pictures in this code below.

.mbtlist {
  list-style-type: none;
  overflow: hidden
  }

  .mbtlist li {
  margin: 0px auto 20px auto;
  clear: both;
  color: #666;
  font-family: Helvetica;
  font-size: 12px;
  border-bottom: 1px dotted #ddd;
  padding-bottom: 10px;
  }

  .mbtlist .mbttitle {
  font-family: oswald;
  font-size: 16px;
  color: #0080ff;
  font-weight: normal;
  text-decoration: none;
  }

 .mbtlist .mbttitle:hover {
 color: #00A5FF;
 }

font-family:georgia;
font-size:15px;
font-weight:bold
}
.mbtlist div span {
 margin: 0 10px 0 0;
 display: inline-block;
 }
.mbtlist span {
 display: block;
 margin: 5px 0px 0px;
 padding-right: 5px;
 }
.mbtlist .imore {
 font-size: 16px;
 font-weight: bold;
 text-decoration: none;
 color: #666;
 line-height: 0.7em;
 }
 .mbtlist .mbttitle .imgbox {
  max-width: 80px;
  max-height: 65px;
  margin: 0px 10px 10px 0px;
  padding: 6px;
  box-shadow: -1px -1px 4px #777;
  display: inline-block;
  vertical-align: top;
  text-align: center;
  overflow: hidden;
  }
 .mbtlist .mbttitle .imgbox > img{
  width: 100%;
  vertical-align: middle;
  }


 .mbtlist li:first-of-type .mbttitle .imgbox
  {
  display: block;
  width: 100%;
  max-width: unset;
  max-height: unset;
  }

<script>
  function getPosts(json) {
  var posts = "<ul class=mbtlist>";
  for (var i = 0; i < json.feed.entry.length; i++) {
  var title = json.feed.entry[i].title.$t;
  var url = json.feed.entry[i].link.pop().href;
  if (json.feed.entry[i].media$thumbnail) {
    thumbUrl = json.feed.entry[i].media$thumbnail.url;
    thumbnail = thumbUrl.replace("/s72-c/", "/s" + 200 + "/");
  }

  posts += "<li><a class='mbttitle' href='" + url + "'><span class='imgbox'><img src='" + thumbnail + "'></span>" + title + "</a></li>";
}
posts += '</ul>';
document.getElementById('container').innerHTML = posts;
  }
