[thelist] Image problem in FB

[rodrigo at cedha.org.ar]

Hello list:
 Im developing this site: http://www.cedha.org.ar/desarollo
 The problem is, that image is cutted into little image pieces, but I
seems Firebird doesn't display it correctly, but it displays good in IE.
Don't know what is the error, maybe it's in the XHTML code, or in the
CSS.
 Can anyone help please ? Im really confused about this.
 Greetings from Argetina,
