有沒有辦法讓博客從圖像中獲取外部網址（這已經是帖子的一部分），因此它可以生成縮略圖？從外部網址發佈縮略圖不會出現在博主
我之前從外部或Picasa網址生成縮略圖的模板，但是我需要更改模板來創建響應式模板，現在，新模板只會選擇上傳到Picasa的圖像來生成縮略圖。
下面是最近的職位列表中的部分代碼：
<b:if cond='data:post.thumbnailUrl'>
<a class='wdxthumb' expr:href='data:post.url' expr:title='data:post.title'>
<img class='post-thumbnail' expr:alt='data:post.title' expr:src='data:post.thumbnailUrl'/>
</a>
<b:else/>
<a class='wdxthumb' expr:href='data:post.url' expr:title='data:post.title'>
<img alt='no image' class='post-thumbnail' src='https://lh3.googleusercontent.com/-VnJqhx42r-c/UfFWlD-sF_I/AAAAAAAAAQI/rT3sYPba2dY/s271-Ic42/logo3.jpg'/>
</a>
</b:if>經與相關的帖子（在後頁）同樣的問題，這個時候使用javascript：
<script type = 'text/javascript'>

</script>它也發生在熱門列表，Notícias和主頁底部的其他4個窗口小部件上。 你可以在這裏看到問題：hondanewspot.com
通過互聯網唯一的解釋我可以找到的是，博主只能從上傳到picasa和其他一些圖片生成縮略圖。但奇怪的是，我的其他模板運行良好。
在此先感謝您的幫助。
