Widget do not show category picture

[4max.jung-1439492842 0]

I have a category page with text and associated category picture - see the link.

https://vse-o-krmivech.cz/krmivo-pro-psy/faktory-hodnoceni/obsah-zivin

The problem is that this picture is not printed on the widget preview - see attachement.

The same result is with a picture included into category text with the help of the text editor. What do I wrong?
