How to set the right image from K2 images and Joomgallery Photo

Jeroen,
We're glad you found JFBConnect too!

With the 4.0 release, we added the functionality to the Open Graph area to use the first image in an article automatically as the image tag. In the Social configuration area, in the Open Graph tag, just enable "Use first image in article for default" and that will work for K2 and Joomla content. One caveat, and it may be your issue, is that this only works for images 'in' the content. Not the separate article tab in K2 that let's you specify an article image.

In addition, the {JFBCGraph image=http://site.com/image.jpg} tag can be inserted directly into the templates of JoomGallery or Eventlist. Unfortunately, I'm not familiar with those components, but if there's a template override you can create, or if you know where the image is being generated and sent to be displayed to the user, you can add that tag and hopefully use whatever variable is available to you for the image. The JFBCSystem plugin will detect this tag and should properly insert the Open Graph image tag for you.

Hope that makes sense. You may be able to ask the developers of those components about how/where you could identify the first image shown, and we can help you from there.

If you need anything else, just let us know,

Jeroen,
When you update the Open Graph tags, it can take Facebook 24 hours (or so) to re-scan your pages and see the changes. You can use their URL debug tool, below, to check immediately how they see your page with the updates:
developers.facebook.com/tools/debug

Check that out and see if the image tag is correct. If not, let us know the URL of a page that you're trying this on, and we'll see if we notice any common errors or problems.

As for the JomSocial wall, I'm not exactly sure what you're saying. JFBConnect doesn't post Facebook comments into the user's wall, so not sure how that's happening. I may just be mis-understanding the problem.

Thanks,
Alex

Jeroen,
The "Use first image in K2" setting only works for images in the articles text. It doesn't work with K2's "Image" tab where you can set an image for that article. The reason is because, in our content plugin, we're only handed the text of the article by K2. We can't see the 'item image' that is set directly. It's something we're looking into to figure out how to do, but don't have any great solutions right now.

So, in this case, we won't be able to automatically add the image, but you can do so manually by placing the following text in the article:We'd recommend placing that tag at the end of your article so that it doesn't mess with some of the K2 logic for using the first 100 chars of intro text for certain things.

I know this isn't optimal, but hopefully, helps you accomplish what you're trying to do. We'll be looking to find a better solution for using the Item Image, and will update JFBConnect in a future release with that ability.

Hope that helps explain,
Alex

Jeroen,
Thanks for sharing what worked for you. We'll definitely be looking into this for the 4.1 release, and appreciate the code snippet. Always good to have a starting point

Sounds like you're all set up now, but if you need anything else, you know where to find us!

Thanks again,
Alex
