[TYPO3] Swapping order of headlines and images of content elements

[Andreas Balzer]

Hi!
I use css styled content elements. Some of the "text with image" content 
elements first show the image and then the headline of the content 
element and third the text. How to swap the order of appearance to 
headline, image, text? I didn't find it in Template Object Browser. Can 
you tell me where I have to look for it and how to change it?

Thanks in advance!
