I did change of Master key as recommended in other thread, but no change. What is interesting is that on Social Debug web page, article with the image is displayed correctly. Only one error they highlight that is rel=canonical and og:url having different content that might be the casue that Facebook does not show correctly the article.
Url is: tangodo.cz/cs/vyuka/skupinove-lekce#

The og:url tag definitely seems incorrect. It's showing as:
<meta property="og:url" content="http://www.tangodo.cz"/>
That means that Facebook and other networks will only use the data from your home page to represent the page you linked to. If you set that tag in the JFBConnect -> Open Graph -> Settings -> Default area, you should remove that setting. Then, re-run your page through the Social Debug tool to ensure it's correct. That should get you going, but if not, just let me know.

You are right, I deleted Open graph setting and now Social Debug page shows no problem and article is there with correct link and image, all meta tags are good. But if I click Share button on my page, There is nothing in the popup window :-( Where can be a problem?

The share button works a little differently than the Facebook Like button, or other social sharing widgets. It can take Facebook a few days to re-scan the page for use with the share button. I'd recommend using the Like button to test what appears or use Facebook's own URL debug tool, which should return the same info as Social Debug:
developers.facebook.com/tools/debug

I hope that helps explain, but if you need anything else, just let me know.

Thanks,

It is quite strange, because on Social Debug it is fine, but using Share from there shows exactly the same problem not showing anything in the popup box. Trying Facebook debug tool writes some error that "og:type is missing, but in the Social Debug it is there as meta tag. Unfortunately even Like button is not working, nothing in the popup window. So far I cannot use it.

After disabling all gzip features in one merge plugin and on joomla then Facebook debug start to show correctly tags. So now it works. Just for my understanding, is there any chance to get image resized or I need to take care of that before and prepare the correct size in advance manualy?

Facebook will try to automatically resize images as necessary.. but generally, they'll only make them smaller. It's recommended to use as large of images as possible so that Facebook can crop them as necessary.

I'm glad you found the issue with your optimization extension. Not sure why it was causing problems, but hopefully you won't run into it again going forward.

Thanks,
Alex
