I18N Gallery for Background-Images

[soy]

Hi,

I've started a new toppic for this, because it may be interesting for others, too.
I need a randomly changing background for my client, always full-screen, always centered. Second point is easy and made in a few seconds with CSS3:

Code:

background: url(../img/bridge.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;

Second part is a little bit harder, if I keep in mind, that the client needs to update these images as easy as possible. So I thought this may be possible with the I18N Gallery, too? Because of its easy upload function. Or are there other ways?

Best regards,
Soy.
