facebook - og:image Open Graph Warnings image size

Question

I check my url because facebook don't use the image that I set on og:image

url fb check

My image is: 639x649px 486kb But fb use this picture: 300x443px 97kb

The warning said:

og:image should be larger: 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 'url from image, size: 300x443px 97kb' will be used instead.

But when I try to create an image 1500x1500px, upload to server, refresh, and check again the link on top, the results are the same.

Answer 1

My experience with Facebook made me doubt that computers are deterministic machines :)

Sometimes it will accept image of any size (between 200 and 1500px), sometimes complain that image is too small (og:image should be larger) even if image is squared and bigger than minimum size (e.g. 400x400px). I had situations where the same link showed all 3 og:images in linter and in FB status field, then suddenly 2 weeks later stopped working and started showing only one image while trying to share it in FB status field (linter still showed all 3 images), and vice versa. Sometimes FB seems to have problems with different domains (e.g. page is on www.example.com and og:image on www.picdumpexamplesite.com), sometimes it doesn't mind...

IMHO it's heavily broken, and the best you can do is:
- make images squared, rounded to "hundreds", e.g. size 300x300px
- host them on the same server (same domain name)
- use jpg
- avoid any "strange" chars in filename (I use only letters and numbers)
- pray that something of the above works :)
