[TYPO3-ttnews] imgAltTextField and tt_news 2.5.0

[Stephan Bauer]

Hello,

I would like to use the config option "imgAltTextField = imagecaption"
to show the text in field caption also in alt and title but in the generated 
site
the fields alt and title are empty (alt="" title="").

I can see the imgAltTextField in the object browser but there is no 
description
in the manual.
I found a description in a older manual (version 1.6.3).

Is there something wrong in the latest version or is it my fault?

Thanks

Stephan
