The layer needs to be turned on. By default with the CGI all layers are turned off unless they are "STATUS DEFAULT". To fix, either:
1) set the layer "tif" status to DEFAULT or
2) change your call to the CGI to something like: http://localhost/cgi-bin/mapserv?map=/var/www/sviluppo/workshop-5.4/prova.map&mode=map&layer=tif

I have added this line in .map file:
CONFIG "MS_ERRORFILE" "/tmp/mapserver.log"
And this is the output:
[Wed Jul 7 23:18:21 2010].797918 CGI Request 1 on process 4712
[Wed Jul 7 23:18:21 2010].798507 msDrawMap(): Drawing Label Cache, 0.000s

[Wed Jul 7 23:18:21 2010].805731 msFreeMap(): freeing map at 0x8dd72a0.
May be useful?
Thanks.

How I have to set EXTENT parameter? What are the correct value?
Can you take me an example?
Thanks a lot.
Michele.

The first thing that I see is that the EXTENT needs to be corrected in your map file.

Can you also include a sample request that gives you a blank map?

Hi, thanks for help me.
1. Is your file indeed georeferenced?
Yes it is georeferenced.
2. The style definitions look good, the only thing I see missing are
the class names. Not sure if that matters if you don't display a
legend.
How I have to modify the .map file for add this information? Can you write me an example?
3. Have you got the map file working without the class definitions?
I.E get a grayscale map?
If I write this file map I have always blank image:
MAP
NAME "prova"
CONFIG "PROJ_LIB" "/usr/share/proj/"
STATUS ON
SHAPEPATH "./"
SIZE 494 531
PROJECTION
"init=epsg:4326"
END
EXTENT -154 -57 26 33
DEBUG 5
WEB
IMAGEPATH "/var/www/sviluppo//workshop-5.4/tmp/"
IMAGEURL "/sviluppo/tmp/"
END
LAYER
NAME "tif"
DATA "prova.tif"
STATUS ON
TYPE RASTER
OFFSITE 0 0 0
END
END
4. Have you attempted to discover what is wrong by looking at the
mapserver log? You will need to enable logging in your map file.
How I can enable it?
I have upload the image on another upload web service:
http://www.megaupload.com/?d=K8SY5IP3
<http://www.megaupload.com/?d=K8SY5IP3>you can try this if you want.
Or can you try with a your image?
Thanks again.
Michele.

For some reason I can;t get to the file you posted, so I have a few question.
1. Is your file indeed georeferenced?
2. The style definitions look good, the only thing I see missing are
the class names. Not sure if that matters if you don't display a
legend.
3. Have you got the map file working without the class definitions?
