Yes. The best thing to do is take screen shots from several zoom levels if you have scale dependent SLD rules. If all the colors are the same at all zoom levels then you can just use one zoom level. > And doesn't the created palette need a geo referencing file as well to > be used? > Nope. What the palette is doing is picking which are the most important 256 colors out of the thousands that a png24 renders. Then it just sets those as the ones for GeoServer to use when rendering, which makes things much faster. And generates the smaller images. So all the palette contains is a list of those 256 colors - no geo referencing needed. > One completly other thing I couldn't find out!
