[OpenLayers-Users] Map overview..

[helmi]

Try play around with parameter values in your OverviewMap, example:

var layer = new OpenLayers.Layer.WMS( "Malaysia",
                "/tc/tilecache.cgi?",
                {layers: 'basemap', format: 'image/png' }
                );
var ov = new OpenLayers.Control.OverviewMap({minRatio: 16, mapOptions:
{maxResolution: 0.02197265625, minResolution: 0.0000858306884765625},
layers:[layer]});
