Facebook Sharer Doesn't Get Thumbnail

Question

I tried meta property="og:image" , meta property="og:image:security"and link rel="image_src" but when i click link, sharer doesn't get thumbnail. It shows title, description and url. I tried to rescale the images to 90x90, 200x200 and 500x500 but nothing happened. Here is the code:

<meta property="og:url" content="URL">
<meta property="og:title" content="TITLE">
<meta property="og:description" content="DESCRIPTION" />
<meta property="og:type" content="website">
<meta property="og:image" content="IMAGE">
<meta property="og:site_name" content="SITE NAME">

<a href="https://www.facebook.com/sharer/sharer.php?u=url" target="_blank">Share on FB!</a>

PS: I got https too and i also tried on it.

Here is the output:

Answer 1

This could be for a number of reasons, but without seeing your actual code (not blanked out with IMAGE, SITE NAME etc) I can only hazard a few guesses.

1. Your site is hosted locally or password protected

   It's sometimes a silly mistake people make, if you're developing this locally and you put in a locally hosted image as the og:image content then facebook wont be able to load the image correctly.

2. Not a valid URL

   Load the og:image URL and see if loads. If it doesn't, that's your problem.

3. Your image is invalid. This is what facebooks documentation has to say on the image properties:

   og:image - An image URL which should represent your object within the graph. The image must be at least 50px by 50px, although a minimum 200px by 200px is preferred and 1500px by 1500px is recommended for the best possible user experience. The image can have a maximum aspect ratio of 3:1. We support PNG, JPEG and GIF formats. You may include multiple og:image tags to associate multiple images with your page. (Note: image sizes must be no more than 5MB in size.)

4. Facebook has blocked your domain

   Unlikely, but possible. See below regarding using the facebook debugger.

You are able to use Facebooks debugger - just type your URL in and it will give you all the information you need. Including the og:image property.

If nothing is picked up, make sure you're including the tags correctly in your page, which you can see here.

If absolutely none of the above works, and you really can't get anything to work for you, you can include the URL directly in the share URL link - I've made an example here for you.
