Hey Massaki,
I’ve dropped IE8 support for all themes since the beginning of 2014, following ThemeForest’s lifting of this requirement. What you can do, though, if you want the website to show images in IE8, is transfer the background CSS rules into the theme’s “ie8.css” file, like this:
#page-holder-12 {
background-image: url('http://www.facem.jp/wp-content/uploads/2014/04/FaceWaterSplashWEBVersion.jpg');
background-repeat: no-repeat ;
background-size: cover;
}
#page-holder-35 {
background-image: url('http://www.facem.jp/wp-content/uploads/2014/04/fundo.jpg');
background-repeat: repeat ;
background-size: initial;
}
#page-holder-46 {
background-image: url('http://www.facem.jp/wp-content/uploads/2014/04/access.jpg');
background-repeat: no-repeat ;
background-size: cover;
}
Sincerely,
