In MW 4.8.6 Final Release:

The toolbox > Raster > Clip Grid with Polygon does not allow to specify raster Jpeg images to be clipped.

Why not?

Gerd,

I have no idea.
I think this method is using the old mwGeoProc method. Those methods are a bit restricted because not everything is implemented.
For v4.9 we will use more GDAL methods and then it should work.

Can you report this to bugs.mapwindow.org. I'll assign it to Sergei so we won't forget it.

Thanks,

Paul

For what it's worth, we implemented an algorithm in DotSpatial for clipping a raster with a polygon that out-performed the MW4 version by a large margin in our test.
