Set image as background

[Jason Brawner]

Got a dumb question....
I've developed a website for a client that posts pictures for people to come and download and email to friends. My client has requested that I give the ability to set the photo as the background of the users desktop. I know this can be done by right-clicking on the image and clicking on the "set as background" (ie). My client would like this to be a button on the page
Is this possible thru JavaScript?

There's certainly no standard way of doing this. I'd suspect that IE has Windows-specfic extensions to do this so I'd poke around the Microsoft site a bit.
Whatever solution you come up with will probably be limited to Windows and IE.
hth,

Can you imagine if web sites *could* arbitrarily run JavaScript code to change the Windows wallpaper? What a perfectly sneaky way to advertise.
The short answer is that it's not possible in JavaScript. Not even using IE extensions.
There is a "external.AddDesktopComponent()" method that will add things (such as images) to the Active Desktop, but users will have to have Active Desktop turned on and it normally isn't.
But that's not the same as wallpaper. The closest you might come is to create your own BHO (Browser Helper Object) or ActiveX control and hook into the Windows API. But that's a lot of work just to set the background wallpaper...

Scott,
Your right about the advertisers. Now that you put it in that perspective the answer is obviously NO. I guess I wasn't thinking...
Thanks for the replies.
