listbox

Javascript:

     function changeMap()
    {
       imagesource =  "http://maps.google.com/maps/api/staticmap?size=500x500&maptype=hybrid&zoom=16&sensor=false&markers=color:blue|label:K|28.541250,77.204100" ;
       mapimage.src  = imagesource ;
    }

Html code :

         <select name="choose_colony" id="choose_colony" size="8" onchange="changeMap()" style="float: left;">
        <option value="1" >Big apartments</option> 
        .
        .
        <option value="999">plaza</option>
        </select>
        <img name="mapimage" src="" alt="Select your Colony" style="float: right;">

In this whenever a selection on the listbox is made changeMap is called and an image is loaded. What I want is for a different image to be loaded everytime depending upon the option selected .

there will be over 2000 entries in the listbox. Considering this what is the best way of going about this ? I can figure out the if/then part , but my main question is whether its ok to put all the 2000 long image addresses in the html file itself ? I hope I was clear ..
