Or, just a straight mode=legend request to the CGI if you are using MapServer. You can pass in your extent, that will manage the scale-dependent layers.

Will the map file remain the same for this? I did try using mode=legend in my request and added that to a separate DIV.But the request doesn't seem to be generating any image. This is how my map file looks. I've not pasted the entire contents as its too big.

legend
   status on
   imagecolor 255 0 0
   position ul
 end
 layer
   CONNECTIONTYPE postgis
   name india_states
   CONNECTION "user=postgres dbname=ibp host=localhost"
   group world
   type polygon
   dump true
   METADATA
      "wfs_title" "Factbook Metadata"
      "gml_include_items" "all"
      "wms_feature_info_mime_type" "text/html"
   END
   template "template.html"
   projection
     "init=epsg:4326"
   end
   transparency alpha
   status on
   data "topology from india_states using unique id using SRID = -1"
       CLASSITEM "state"
       CLASS
               NAME "JAMMU & KASHMIR"
               EXPRESSION "JAMMU & KASHMIR"
               STYLE
                       COLOR 191 191 155
                       OUTLINECOLOR 000 000 000
                       #antialias true
               end
       end
     CLASS
               NAME "HIMACHAL"
               EXPRESSION "HIMACHAL"
               STYLE
                       COLOR 245 226 188
                       OUTLINECOLOR 000 000 000
                       #antialias true
               end
end And this request is like this as per the example i found here :http://openlayers.org/pipermail/users/2008-September/007495.html
var legenddiv = document.createElement('div');
legenddiv.setAttribute('id','legend');
legenddiv.innerHTML = '<img src = "http://localhost/cgi-bin/mapserv?mode=legend&map='+mapfile+'"</img>';
document.getElementById('map').appendChild(legenddiv);

Thanks & regards,

    Also, you might want to consider making a separate
    GetLegendGraphic WMS request and putting the legend in a separate
DIV element in your web page.
    Just an idea.

        and search for untiled. There's a "WMS Untiled" example you
        can view the source of. The singleTile option goes in the
        "options" object as opposed the "params" object. Params get
        passed to the WMS service, options are handled by OL.

        Hi Steve,
        It would be great if you can give me an example or tell me
        where it is
        usually set in OL.
        Thanks for your help.
