[TYPO3-content-rendering] cron_cssstyledimgtext alt & title

[Raphael Matter]

hi!
i use CSS STYLED IMGTEXT (cron_cssstyledimgtext 0.3.0) for content type 
image / textimg.
in the FE the <img> only shows alt="" and title="", although i've 
entered alt and title in the BE.
what can i do to display images with the correct alt and title text?

thanks. raphael
