[XXE] align table or picture with css

[Rémy Bruch]

Hello,

Can i align a picture or a table (when the size isn't 100%) with the css  ?
It's always align on the center of my page for the picture and on the left for 
the table. 
picture {
    text-align : concatenate(attr(align));
    content: image(attr(path), attr(width), attr(height));
}

thanks
