K2 and like button doesn't work properly

First, make sure you're using JFBConnect 4.1, as that updated how K2 open graph images are detected. If you're using that, then JFBConnect is set to always use the medium size image set for the article, if it exists.

If you're running 4.1 and this still doesn't fix it, let us know a URL we can see a K2 article on, and we'll help how we can.

With 4.0.x, JFBConnect will only use the first image within the content as the automatica Open Graph image. In 4.1, we added the feature to use the Item Image that is set for the article. So, until you upgrade to JFBConnect v4.1, you'll need to explicitly set the Open Graph image tag in the article like:
{JFBCGraph image=http://site.com/link-to-image.jpg}

Hope that helps,
Alex

In category view, we don't set the Open Graph tag for that page because there are many articles and there's no way to know which article is the image for 'that' category page. However, the Like button for each article will be for the destination URL. On that destination URL, the image should be set, and that's what Facebook will use. So, you shouldn't need the image set on the category page, unless you want a Like button for that page (not each article). In that case, I believe you'd need to manually set the {JFBCGraph image=http://site.com/image.jpg} tag in the categories description to force it for that view.

Hope that all makes sense, but if not, let us know.

Unfortunately, that's not how JFBConnect works right now. We'll look into adding that functionality, but I can't guarantee we will. I don't think your usage case is the most common, and we need to make sure JFBConnect works for all usage cases.

As for the Like button in general in the category view, when JFBConnect adds it, like I mentioned before, the button will always point to the 'final' destination URL for the article, not the category view URL of the current page. Are you using the JFBCContent plugin to automatically add the Like button? If so, then I still think it should use the final article image. If not, let us know. If you're using a custom button on the page though (for that category URL), then that would be another indicator that you'd need some way to specify the Open Graph tags manually as well.

Hope that explains,

If you're logged into Facebook with an administrator account, above the comment box, there is a "Settings" button. Click that, and in there is the option to allow other authentication providers. Once enabled, it will apply to all comment boxes on your site.

If you can't find it there, you can go to the Comment Moderation Tool from Facebook and hit the Settings button there for the same options:
