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

	ENDEND
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

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?
