[XeTeX] I can't include a gif image

[Francisco Chaves]

Hi all

I don't know how I can include a gif image. I am using

{\XeTeXpicfile "escudo.gif" height 2cm}

but XeLaTeX gives me  the following error

***************************
! Unable to load picture or PDF file 'escudo.gif'.
<to be read again>
                   }
l.5 {\XeTeXpicfile "escudo.gif" height 2cm}
***************************

Thanks in advance

Francisco
