我正在使用 joomla。在 FB 调试器中测试页面时： http: //tommigotphotography.com/en/galleries/wildlife
它正确找到了所有图像，但警告我提供的 og:image 太小，它会选择它为缩略图找到的图像之一。
但是，我所有的图像都是最小 400 像素。
我使用了一个名为 Content - Perfect Link with Article Images on Facebook PRO 的 joomla 插件来强制动态生成 og 属性，旨在保证我的文章中的所有图像都被 FB 拾取。
根据 Graph API 和抓取的 URL 输出，该插件似乎工作正常。
调试器如何找到所有图像，所有图像都大于 FB 要求并且仍然抛出我：
Provided og:image is not big enough. Please use an image that's at least 200x200 and preferably 1500x1500. (Maximum image size is 5MB.) Image 'http://tommigotphotography.com/media/djmediatools/cache/700x400-toheight- images_wildlife_wildlife-200902201651-tmp.jpg' will be used instead.

我要在 FB 上发布一些公告，直到 FB 让我能够选择合适的图像，我才能这样做。
我希望我已经彻底了解了他的细节。
干杯，汤姆
