[TYPO3-english] Colorbox rzcolorbox css class missing

[Martin Mädler]

Hello,

is somebody using the jQuery Colorbox extension rzcolorbox and might 
able to help me along? I'm using TYPO3 4.5.2 and rzcolorbox 1.3.4.
For testing puposes I added a content element of type Images on my 
homepage. Under Behavior I checked "Enlarge on Click" and specified an 
url to a larger version of the same image.

My problem is that the the link doesn't open a colorbox popup, but the 
larger image in a new tab instead. I looked at the generated source and 
the Javascript and CSS references are there:

<link type="text/css" media="screen" rel="stylesheet" 
href="typo3conf/ext/rzcolorbox/res/style1/css/colorbox.css" /><script 
type="text/javascript" 
src="typo3conf/ext/rzcolorbox/res/js/jquery-1-4-3.js"></script>
<script type="text/javascript" 
src="typo3conf/ext/rzcolorbox/res/js/jquery.colorbox.js"></script>
<script 
type="text/javascript">jQuery(document).ready(function(){jQuery(".rzcolorbox").colorbox({current:"Bild 
{current} von 
{total}",opacity:"0.85",transition:"fade",speed:350,slideshowSpeed:2500,previous:"voriges",next:"nächstes",close:"schliessen"});});</script>

I noticed however that the css class "rzcolorbox" is not assigned to the 
link tag in question. In fact I can't find it anywhere within the 
generated html file.

In the Backend under Behavior (when editing the page content), I'm 
missing any Colorbox specific settings. Shouldn't there be an option 
named "Colorbox Slideshow" as described here?

Thanks in advance
