Q:

html/css adding an image for every for every listitem in my menu

I have a listmenu (buttons) and I want to add a small image onto the button 
in front of every listitem text (link1,2,3,4) with a padding-left of 5 pixels,
it should also stay when I hover with my mouse over a button. 
But I cant seem to find a way how to do it.
image that you can use as an example:

this is the code for my buttonlist:
html:
<div id="menupadding">
<div id="menu">
 <ul>
<li><a href="#">link1</a></li>
<li><a href="#">link2</a></li>
<li><a href="#">link3</a></li>
<li><a href="#">link4</a></li>
 </ul>
</div>
</div>

css:
#menupadding {
    padding-top: 100px;
    padding-left: 302px;
}

#menu {
    margin:0;
    padding:0;
}

#menu li{
    display:block;
    list-style:none;
    padding-bottom:1px;
}

    width: 140px;
    margin:0;
    padding:1px;    
}

#menu li a{
    display:block;
    font-family:Tahoma, Geneva, sans-serif;

    background-image: -o-linear-gradient(bottom, rgb(0,65,139) 14%, rgb(33,42,66) 89%, rgb(0,0,0) 100%);
