Hi

I have a website and want to allow users to click on the main background image and be able to set this as their desktop wallpaper.

Is this possible with javascript?

thanks

No, this is not possible through JS. Otherwise JS would have to much access on the PC Enviroment wich could be used by attackers.

You could use a Java applet for this job, but today it's not a good idea to make use of Applets on Websites were it's not quiet necessary.

ok thanks .

If it was a hardcoded image rather than a backgound image would this make any difference?

Thanks

No, the thing is, that it's not possible to modify the OS configuration / registry of the users enviroment.
So it doesn't matter wich kind of object you are serving, if you can't manipulate the desktop wallpaper settings.

Me too, I don't think there's a cross browser way to do that. The user need to do it manually or using a plugin :

Or in FF: Right click on page, view background image, set as desktop image
Works just fine

hi,

ok thanks. Do you think it is possible to just save the image with javascript then? Rather than saving and setting as wallpaper?

Cheers
Paul

Nope. Not a chance - not unassisted JS
