Hey Stephen, if you could send us examples at [email protected], we’re happy to take a look at your posts.

To be clear, the only thing NationBuilder does is set the page’s image meta tag URLs for Facebook to pick up (either to your site’s default image or the one you’ve specifically uploaded to that page). The choice to use or ignore the meta image is on Facebook’s end.

Also thought it would be worth including Facebook’s best practices for image sizing: https://developers.facebook.com/docs/sharing/best-practices#images.

For my NB blog I can set the social image I want to use for each individual blog post which is important to me when I want to use different content-related social images that match up with the post. That works like a charm every time. When I don’t set a social image with the individual blog post, NB chooses a truncated portion of my hompage header image as the social image. I’m not sure why. In the past, NB used to use our logo, but it didn’t size properly in FB, and came out cut off. The homepage header is a new design element that was added in the last six months, so maybe NB prefers to grab that by because it is in excess of 600 pixels?

I’m mostly satisfied that I can share blog posts varying social image I choose…but it would be nice to know why NB grabs my header image. It probably has something to do with the size of the header vs. the size of the logo…so I’ll keep trying to find the magic proportion to force NB back to our logo.

We’ve gotten reports of customers who have used the debugger and are still seeing the wrong image (often, their logo) shared on automatically generated posts when multiple people on Facebook share the page. For these kinds of posts, Facebook may ignore the provided image if another image in excess of 600 pixels in width is present. Often, a logo doesn’t need to be that big, so you can try reducing the size of your logo to resolve this.

Seriously how do you remove a social image from a page/post — I don’t want to replace it, I want it to go back to EMPTY

Hey Betsy,

What do you mean remove it? Do you mean that facebook is picking up the wrong image? Or that you don’t want any image at all on the page?

Any way to remove the social image you choose instead of having to redo the whole blog post?

Google + seems to pick up the image fine but FB does not.

I am having similar issues to the people who have commented already. When I select a custom thumbnail for the social media posts it still defaults to the site logo image and is incorrectly sized.

Hi Stephen,

It can take some time for Facebook to update images – to expedite that update, you can drop the page url for their debugger tool here: https://developers.facebook.com/tools/debug

This should clear the cache and update the image accordingly.

I’ve done this for a petition, but it doesn’t seem to matter. It still defaults to the logo, which is sized improperly, and distorts when shared on Facebook. Any thoughts?

Fantastic. Great response!
