Robert,
Without seeing a code example, my first guess is that the opacity option
isn't in the right place in the Layer constructor.
Initial layer opacity gets set in the 'Options' section when you
construct the OpenLayers.Layer
Here's an example creating a layer from a WMS:
var layer_name = new OpenLayers.Layer.WMS(
"Layer name here",
"/geoserver/ows",
{
layers: 'public:roads',
srs: 'EPSG:4326',
format: 'image/png',
transparent: true
},
{
opacity: 0.8,
isBaseLayer: false,
visibility:true
}
);
Note that the 'opacity' setting is in the second set of 'squiggly
brackets' {} (this is where options are set). I think lots of people get
confused as to where to put settings/options like this.

I am attempting to create a map which shows a satellite image over a
basemap. The problem is that the satellite image is too opaque such
that the basemap isn't visible. I've tried setting opacity to some
small amount but have not seen any affect.
