Excellent, I'll go look into this and give it a try. Many thanks

I don't know what your parameters look like, but you can quite easily build a request URL doing something like this: var params = { foo: bar, ping: pong }; var layer = new OpenLayers.Layer.WMS( "Custom Layer", "http://url.to.service/";, params, {singleTile: true} ); This will automatically request your web service. You don't need to give it a lat/long yourself as this will be done for you! Btw: I assumed that your layer is a baseLayer. If it isn't and the projection of your layer is different from the baseLayer one, you'll need to do some more work. Good luck!
