Hi
I saw you have changed the image size and it works fine with fb posting.
I did the same thing with another image but it does not work.

i use gwenview to resize my pictures.
i used to post my products on fb a long time ago but the problem started about 45 days ago.
something else is happening, please tell me what u did so i can do the same!
Regards
Dimitris
