I saw this line on the source of the page.
<body style="background: url(http://secondworld.wordpress.com/wp-content/themes/pub/contempt/images/blue_flower/bg.jpg) repeat-y top center #aaa fixed;">
Ok, I've got all option for change CSS style, we use "Contempt par Michael Heilemann" for template.
The problem is that I can't put any background image on my body ... of course there's a style property in the HTML ...
How can I put a 20*20 image repeat ... if there is a damned line of design in the html that I can't edit... ?
