[GRASSLIST:4104] stupit newbie question on import raster

[UK]

Hi everyone,

I have a seemingly stupid newbie problem: I'm runnig the OS X port of 
Grass 5.7 and after trying the sample spearfish location  everythings 
seems to be installed ok. In particular I'm able to display the data. 
In contrast to that  I was not able to import or visualize some other 
data, e.g. some satellite.jpg. Here is what I did according to the 
manuals:

first I created a location of xy-type:

GRASS 5.7.0:~ > projection: 0 (x,y)
zone:       0
north:      1239
south:      0
west:       0
east:       1501
nsres:      1
ewres:      1
rows:       1239
cols:       1501

The picture dimensions are 1501x1239 pixel and type is jpg. I opened a 
display by d.mon x0. Next I imported the picture by the
tcltk front-end:

r.in.gdal
input=/Users/kuhli/Desktop/Celestia-doc/EarthImage/
aster_vesuvius_lrg.jpg output=vesuv -o

CREATING SUPPORT FILES FOR vesuv.blue
SETTING GREY COLOR TABLE FOR vesuv.blue (8bit, full range)

when I wanted to display the file I used d.rast  over tcltk-interface:

d.rast map=vesuv.blue bg=white  0%  3%  6%  9% 12% 15% 18% 21% 24% 27%
30% 33% 36% 39% 42% 45% 48% 51% 54% 57% 60% 63% 66% 69% 72% 75% 78% 81%
84% 87% 90% 93% 96% 99%100%

  The d.rast had shown me three files (vesuv.blue, 
vesuv.gree,vesuv.red), I choosed one of them  but the files doesn't 
show up in the
display! Shure I forgot or overlooked something very simple but what? 
If I look at the display with the query-by-mouse function but the 
display seems to be empty ?!  :

285.5266223(E) 860.70299501(N)
vesuv.blue in PERMANENT  (Null)no data

751.44009983(E) 798.85607321(N)
vesuv.blue in PERMANENT  (Null)no data

675.16222962(E) 524.66805324(N)
vesuv.blue in PERMANENT  (Null)no data

What am I doing wrong ?
