ShareThis Facebook share button doesn't find images on a page

Question

The ShareThis Facebook button will only pull the logo as an image to choose from a page. I am not sure why this is the case since I have other images on pages that I am trying to share from. Can someone help me out with this. I am not really familiar with the ShareThis API. Thanks for any help or feedback.

I tried using the Facebook URL Debugger: https://developers.facebook.com/tools/debug. When doing so, Facebook found all the images on the page, but ShareThis doesn't seem to do the same. That is why I am guessing it is a ShareThis related issue.

The client wants the person posting the page/blog post to be able to select the image from the images on the page. This is normally the case with the ShareThis API, but does not seem to do so. Otherwise I would have just used the open graph option.

URL of site: http://www.atranquilnook.com/

1-30-14: I tried specifying an image with open graph meta on a page. The image was larger than 200 x 200, but it still did not work.

This appears to be happening on every page of the site.

Note: I did not build this site. It was built in Adobe Muse by someone else.

Answer 1

This is not a real answer, but I have to use the space here, to get you all the details of what I found out.

On the debugger it says https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.atranquilnook.com%2F :

Provided og:image is not big enough. Please use an image that's at least 200x200 px. Image 'http://www.atranquilnook.com/images/header-home03.png' will be used instead.

Since there is the image with the couple, which is bigger than 200px x 200px, I do not know if this is the answer, but you could try by uploading some bigger image.

Although the whole warning is deceptive, since a line above it states, that there is no og:image.

Answer 2

Looks like you are relying on Facebook being smart enough to find "better" image on your site. What you should do instead is adding a meta tag in the head section of your page.

<meta property="og:image" content="http://www.yoursite.com/img/some-image.jpg"/>

This will tell Facebook exactly what you want to rest of the world to see.
