Please let the user use either Erdas or TIFF external overviews and set compression on/off. In case of TIFF overviews let him choose compresion scheme DEFLATE/LZW/PACKBITS (JPEG maybe too?); hint that DEFLATE compresses best of the 3 and better than Erdas RLC compression too, but that Erdas overviews are supported also in non-GDAL dependent software like ArcGIS and Erdas Imagine, which improves compatibility.

I'm not sure if internal overvievs can be compressed for non-compressed rasters and vice-versa; that's something to investigate.

All this options should be already available (or eventually easily added) in the "build overviews" tool in the raster menu. Please leave feedback.
