I've recently setup Geoserver with GDAL/ECW support. I can create a store in Geoserver which allows me to reference one .ecw file. I can serve this one file over WMS and it works great.

Now i need to serve all 1700 .ecw files as a single layer. I believe this is a function of the ImageMosaic option. However it only seems to allow me to attach one file.

Is there some preparation I need to do to the 1700 files to be able to use them as an ImageMosaic?
