Facebook linter reports og:image is too small, when it is larger than the image it choose instead

Question

Problem:

• linter reports that specified og:image is too small. Image is 628x464.
• linter instead picks a random image from the page which is 380x214, smaller than the og:image!

What the linter shows me:

http://developers.facebook.com/tools/debug/og/object?q=futuremark.com

Background:

We have been happily using 130x110 og:images without problems for the last 9 months. I noticed in the last couple of weeks that pages were no longer sharing the correct image. Using the linter it seems that Facebook recently decided og:images should be at least 200x200. So I have been replacing our og:images with larger examples but the linter still says they are too small.

Any ideas how I can fix this, or is it a Facebook problem? Thanks.

Answer 1

Now I guess that Facebook does not find tags for height and width and considers them null. In my case, next tags fixed this issue:

<meta property="og:image:type" content="image/jpeg" />
<meta property="og:image:width" content="1280" />
<meta property="og:image:height" content="855" />

Answer 2

Did you change how big the image file at http://www.futuremark.com/images/facebook/futuremark-logo.png is without changing the URL specified in the og:image meta tag?

The image itself will be cached if the URL didn't change, so you need to change the URL (or add a cash-busting parameter like ?v=1 to the end)
