facebook - Facebook og:image 有没有办法在使用大图像时强制使用小图像？

Question

当使用 og:image og:image:width 和 og:image:height 标签时，有没有办法在不发送较小图像的情况下强制小方块？似乎这一切都取决于图像大小，但我不想仅仅为这种特殊情况为我们所有的客户创建小图像。

不正确的大共享

即使图像大于 250x250，我也想显示正确的图像尺寸。我想使用 600x600。

The og:image:width and og:image:height tags are not used to specify how small or large the image will appear in a preview. The card display is entirely up to the platform you're sharing your link on.

See Facebook's documentation:

Using these tags will specify the image dimensions to the crawler so that it can render the image immediately without having to asynchronously download and process it.

It's just to tell the crawler what the dimension are so the preview renders faster. It has no effect on the actual size of the image within the preview.

If you want the preview to display a smaller image, you'll have to provide an image with the respective dimensions.
