Background image code question

Here is the page in question,
http://www.theremotedoctor.co.uk/victorias_attic.html

You will see that background code is as follows,

Code:

---

}
body {
    background-image: url("m-images/victorias-attic-background.jpg");
}

---

What is the correct code so when i click on the .jpg image i get the properties box pop up so i can browse for a new image.
Currently this is not available with the code above as you need to know the image name etc & just type it in.

Thanks

Is this something you're looking for in the Developer Tools Console (F12 in most popular browsers)?

When you view a web page in a browser, if you right-click an image you get a 'Properties' popup in IE - is that what you mean?

No
If i need to change the background image for the website.

My other images src etc,i just click on there name and i can browse to the folder & select a new image.
I forgot to mention this is in Dreamweaver so guess its not the correct place to ask ?

Not sure about that I'm afraid. If a student has problems with Dreamweaver in school, I just switch it to split-screen/code view and edit the source directly. Can you do that in this instance?

Yes,
But i was asking why cant i click on the image code and up pop a browser.
They way it needs to be done is that the user knows the name of the image to start with.
I have many images and do not know the name of all of them but i can browse to them and select,job done.
I will ask on the DW forum.

Thanks anyway.
