I have taken Reinhard's advice and included them into the script,

Does this also work if symlink and wrappers (like in a typical TL Windows

 -x  specify a xsize (800)

 -y  specify a ysize (400)

 -S  short form to specify a size, e.g. 800,400

 -s  specify a scale factor in the range 1692-221871572 (3385 = -z 17)
     see: http://open.mapquestapi.com/staticmap/zoomToScale.html

 -z  specify a zoom in the range 1-18 (zoom overrides scale!)

 -i  specify image type {jpeg|jpg|gif|png} (png)

 -c  specify icon color (yellow_1)
     see: http://open.mapquestapi.com/staticmap/icons.html

 -n  specify the icon number (1)

 -o  specify output basename without file extension (osmimage.IMAGETYPE)

 -q  quiet; no output!

 -v  prints version information

 -h  prints help information
