change background image and save

I need a script that changes background image and save. though click the background pic preview to change/save.

You can save things for users using cookies. Presumably your wanting to allow users to change the background?

yes.and i have 0% of javascript knowledge so i dont know how

Two good cookie function:

Code:


function getcookie(name) {
    cname = name + '=';
    cpos = document.cookie.indexOf(cname);
    if (cpos != -1) {
        cstart = cpos + cname.length;
        cend = document.cookie.indexOf(';',cstart);
        return unescape(document.cookie.substring(cstart,cend));
    }
    else {return null;}
}

function setcookie(name,value,sticky) {
    expires = '';
    if (sticky) {expires = ' expires=Wed, 1 Jan 2020 00:00:00 GMT;';}
    document.cookie = name + "=" + value + '; path=/;' + expires;
}


You'll need to design the system how you want your users to change the background image.
- dropdown list?
- Button?
- Upload there own image?
etc...

im thinking button(button is preview of pic),like the one in the tutorial on here but on click instead of onmouseover and save it.
