Facebook不显示所有打开的图形图像 [英] Facebook does not show all open graph images

问题描述

我有一个网页，其中包含一些标准的打开图表 Facebook标签。我的问题是，如果我在Facebook状态消息中放置一个页面的链接，它只显示5张图像中的2张。我的第一个想法是：我做错了，所以我用 FB Debugger ，但它显示所有图像。我等了一个礼拜，但是这个问题并没有解决自己的问题。

有什么想法吗？

错误可能是相关的，但它也没有解决方案： https://developers.facebook.com/bugs/107341092730662

解决方案

该问题与您提供的图片尺寸有关。饲料中外观省略的图像是侧面比例超过3：1的图像。

您提供的页面有5幅图像（比例大于3的图像不被Like Button使用）：

  250×67  - >比例3.73 
 250×186  - >比例1.34（此图像将工作）
 250×166  - >比例1.5（此图像将工作）
 251×59  - >比例4.25 
 172×54  - >比例3.18 
  

有一点是为了避免使用太长或太宽的图像，可能不适合在饲料中显示小尺寸。

I have a webpage with some standard open graph meta tags for Facebook. My problem is that if I place a link to the page in a facebook status message it shows only 2 of 5 images. The 2. and the 3. but not the others.

My first thought was: I did something wrong so I checked the page with the FB Debugger but there it shows all images. I waited a week now but the problem did not solve it self.

Any thoughts on this?

解决方案

The issue is related to the dimensions of images you provide. The images that omitted from appearance in feed are those having ratio of sides more than 3:1.

The page you provided have 5 images (those with ratio more than 3 will not be used by Like Button):

250 × 67 -> ratio 3.73
250 × 186 -> ratio 1.34 (this image will work)
250 × 166 -> ratio 1.5 (this image will work)
251 × 59 -> ratio 4.25
172 × 54 -> ratio 3.18

There point is to avoid usage of too long or too wide images that may not be suitable for displaying in small sizes in feed.
