Facebook like button not showing thumbnail on facebook :-(

[champendk]

Hello Users!

I got a problem.

I have integrated my like button when my users reading articles, but the problem is when i press like on the article and post it to facebook, facebook shows the article in fine view, but without any thumbnail. I have set a picture url from ftp in backend but nothing happends. How can i change the picture, i want it to magically apeer on facebook !

Question number 2.

I wonder why i only get the facebook like button on my articles, i think it should be able to be working with threads, blogs ect ??

Is there a sweet guy who wants to help me with a complete guide for how im setting it up.

Thanks :-)
