After you bring in the file with r.in.tiff, then use
g.region to set the region equal to the file.  If
the file is TEST, then g.region rast=test.  Then
erase the screen (d.erase), and redisplay using

I am trying to create a mosaic of aerial photos. (Thanks to the people who
responed to my previous request for help). I went through a test process 
two photos, and all work well.

I then went back to do the other 28 photos but am running into problems with 

r.in.tiff.  This is what I did for the test.

I converted the jpeg file to tif using XV. The setting were best 24 -> 8,
colour, normal size, and no compression.  I then run r.in.tiff ( down loaded 

from the moon -  r.in.tiff.sun). d.rast displayed the photos

I then converted all the jpeg files , but when I import them with r.in.tiff 
get a black screen.  There are no errors reported.

This is the output from r.in.tiff
